+
+
+## 1.21.0 - 2019-12-29
+
+#### Added
+
+* [#118](https://github.com/shlinkio/shlink/issues/118) API errors now implement the [problem details](https://tools.ietf.org/html/rfc7807) standard.
+
+    In order to make it backwards compatible, two things have been done:
+
+    * Both the old `error` and `message` properties have been kept on error response, containing the same values as the `type` and `detail` properties respectively.
+    * The API `v2` has been enabled. If an error occurs when calling the API with this version, the `error` and `message` properties will not be returned.
+
+    > After Shlink v2 is released, both API versions will behave like API v2.
+
+* [#575](https://github.com/shlinkio/shlink/issues/575) Added support to filter short URL lists by date ranges.
+
+    * The `GET /short-urls` endpoint now accepts the `startDate` and `endDate` query params.
+    * The `short-urls:list` command now allows `--startDate` and `--endDate` flags to be optionally provided.
+
+* [#338](https://github.com/shlinkio/shlink/issues/338) Added support to asynchronously notify external services via webhook, only when shlink is served with swoole.
+
+    Configured webhooks will receive a POST request every time a URL receives a visit, including information about the short URL and the visit.
+
+    The payload will look like this:
+
+    ```json
+    {
+      "shortUrl": {},
+      "visit": {}
+    }
+    ```
+
+    > The `shortUrl` and `visit` props have the same shape as it is defined in the [API spec](https://api-spec.shlink.io).
+
+#### Changed
+
+* [#492](https://github.com/shlinkio/shlink/issues/492) Updated to monolog 2, together with other dependencies, like Symfony 5 and infection-php.
+* [#527](https://github.com/shlinkio/shlink/issues/527) Increased minimum required mutation score for unit tests to 80%.
+* [#557](https://github.com/shlinkio/shlink/issues/557) Added a few php.ini configs for development and production docker images.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#570](https://github.com/shlinkio/shlink/issues/570) Fixed shlink version generated for docker images when building from `develop` branch.
+
+

+
+

+
+* [#561](https://github.com/shlinkio/shlink/issues/561) Fixed `db:migrate` command failing because yaml extension is not installed, which makes config file not to be readable.
+* [#562](https://github.com/shlinkio/shlink/issues/562) Fixed internal server error being returned when renaming a tag to another tag's name. Now a meaningful API error with status 409 is returned.
+* [#555](https://github.com/shlinkio/shlink/issues/555) Fixed internal server error being returned when invalid dates are provided for new short URLs. Now a 400 is returned, as intended.
+
+
+## 1.20.1 - 2019-11-17
+
+#### Added
+
+* [#519](https://github.com/shlinkio/shlink/issues/519) Documented how to customize web workers and task workers for the docker image.

+* [#540](https://github.com/shlinkio/shlink/issues/540) Fixed errors thrown when creating short URLs if the original URL has an internationalized domain name and URL validation is enabled.
+* [#528](https://github.com/shlinkio/shlink/issues/528) Ensured `db:create` and `db:migrate` commands do not silently fail when run as part of `install` or `update`.
+* [#518](https://github.com/shlinkio/shlink/issues/518) Fixed service which updates Geolite db file to use a local lock instead of a shared one, since every shlink instance holds its own db instance.
+
+
+## 1.20.0 - 2019-11-02
+
+#### Added
+
+* [#491](https://github.com/shlinkio/shlink/issues/491) Added improved short code generation logic.
+
+    Now, short codes are truly random, which removes the guessability factor existing in previous versions.
+
+    Generated short codes have 5 characters, and shlink makes sure they keep unique, while making it backwards-compatible.
+
+* [#418](https://github.com/shlinkio/shlink/issues/418) and [#419](https://github.com/shlinkio/shlink/issues/419) Added support to redirect any 404 error to a custom URL.
+
+    It was already possible to configure this but only for invalid short URLs. Shlink now also support configuring redirects for the base URL and any other kind of "not found" error.
+
+    The three URLs can be different, and it is already possible to pass them to the docker image via configuration or env vars.
+
+    The installer also asks for these two new configuration options.
+
+* [#497](https://github.com/shlinkio/shlink/issues/497) Officially added support for MariaDB.
+
+#### Changed
+
+* [#458](https://github.com/shlinkio/shlink/issues/458) Updated coding styles to use [shlinkio/php-coding-standard](https://github.com/shlinkio/php-coding-standard) v2.0.0.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#507](https://github.com/shlinkio/shlink/issues/507) Fixed error with too long original URLs by increasing size to the maximum value (2048) based on [the standard](https://stackoverflow.com/a/417184).
+* [#502](https://github.com/shlinkio/shlink/issues/502) Fixed error when providing the port as part of the domain on short URLs.
+* [#509](https://github.com/shlinkio/shlink/issues/509) Fixed error when trying to generate a QR code for a short URL which uses a custom domain.
+* [#522](https://github.com/shlinkio/shlink/issues/522) Highly mitigated errors thrown when lots of short URLs are created concurrently including new and existing tags.
+
+
+## 1.19.0 - 2019-10-05
+
+#### Added
+
+* [#482](https://github.com/shlinkio/shlink/issues/482) Added support to serve shlink under a sub path.
+
+    The `router.base_path` config option can be defined now to set the base path from which shlink is served.
+
+    ```php
+    return [
+        'router' => [
+            'base_path' => '/foo/bar',
+        ],
+    ];
+    ```
+
+    This option will also be available on shlink-installer 1.3.0, so the installer will ask for it. It can also be provided for the docker image as the `BASE_PATH` env var.
+
+* [#479](https://github.com/shlinkio/shlink/issues/479) Added preliminary support for multiple domains.
+
+    Endpoints and commands which create short URLs support providing the `domain` now (via query param or CLI flag). If not provided, the short URLs will still be "attached" to the default domain.
+
+    Custom slugs can be created on multiple domains, allowing to share links like `https://doma.in/my-compaign` and `https://example.com/my-campaign`, under the same shlink instance.
+
+    When resolving a short URL to redirect end users, the following rules are applied:
+
+    * If the domain used for the request plus the short code/slug are found, the user is redirected to that long URL and the visit is tracked.
+    * If the domain is not known but the short code/slug is defined for default domain, the user is redirected there and the visit is tracked.
+    * In any other case, no redirection happens and no visit is tracked (if a fall back redirection is configured for not-found URLs, it will still happen).
+
+#### Changed
+
+* [#486](https://github.com/shlinkio/shlink/issues/486) Updated to [shlink-installer](https://github.com/shlinkio/shlink-installer) v2, which supports asking for base path in which shlink is served.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* [#435](https://github.com/shlinkio/shlink/issues/435) Removed translations for error pages. All error pages are in english now.
+
+#### Fixed
+
+* *Nothing*
+
+
+## 1.18.1 - 2019-08-24
+
+#### Added
+
+* *Nothing*
+
+#### Changed
+
+* [#450](https://github.com/shlinkio/shlink/issues/450) Added PHP 7.4 to the build matrix, as an allowed-to-fail env.
+* [#441](https://github.com/shlinkio/shlink/issues/441) and [#443](https://github.com/shlinkio/shlink/issues/443) Split some logic into independent modules.
+* [#451](https://github.com/shlinkio/shlink/issues/451) Updated to infection 0.13.
+* [#467](https://github.com/shlinkio/shlink/issues/467) Moved docker image config to main Shlink repo.
+
+#### Deprecated
+
+* [#428](https://github.com/shlinkio/shlink/issues/428) Deprecated preview-generation feature. It will keep working but it will be removed in Shlink v2.0.0
+
+#### Removed
+
+* [#468](https://github.com/shlinkio/shlink/issues/468) Removed APCu extension from docker image.
+
+#### Fixed
+
+* [#449](https://github.com/shlinkio/shlink/issues/449) Fixed error when trying to save too big referrers on PostgreSQL.
+
+
+## 1.18.0 - 2019-08-08
+
+#### Added
+
+* [#411](https://github.com/shlinkio/shlink/issues/411) Added new `meta` property on the `ShortUrl` REST API model.
+
+    These endpoints are affected and include the new property when suitable:
+
+    * `GET /short-urls` - List short URLs.
+    * `GET /short-urls/shorten` - Create a short URL (for integrations).
+    * `GET /short-urls/{shortCode}` - Get one short URL.
+    * `POST /short-urls` - Create short URL.
+
+    The property includes the values `validSince`, `validUntil` and `maxVisits` in a single object. All of them are nullable.
+
+    ```json
+    {
+      "validSince": "2016-01-01T00:00:00+02:00",
+      "validUntil": null,
+      "maxVisits": 100
+    }
+    ```
+
+* [#285](https://github.com/shlinkio/shlink/issues/285) Visit location resolution is now done asynchronously but in real time thanks to swoole task management.
+
+    Now, when a short URL is visited, a task is enqueued to locate it. The user is immediately redirected to the long URL, and in the background, the visit is located, making stats to be available a couple of seconds after the visit without the requirement of cronjobs being run constantly.
+
+    Sadly, this feature is not enabled when serving shlink via apache/nginx, where you should still rely on cronjobs.
+
+* [#384](https://github.com/shlinkio/shlink/issues/384) Improved how remote IP addresses are detected.
+
+    This new set of headers is now also inspected looking for the IP address:
+
+    * CF-Connecting-IP
+    * True-Client-IP
+    * X-Real-IP
+
+* [#440](https://github.com/shlinkio/shlink/pull/440) Created `db:create` command, which improves how the shlink database is created, with these benefits:
+
+    * It sets up a lock which prevents the command to be run concurrently.
+    * It checks of the database does not exist, and creates it in that case.
+    * It checks if the database tables already exist, exiting gracefully in that case.
+
+* [#442](https://github.com/shlinkio/shlink/pull/442) Created `db:migrate` command, which improves doctrine's migrations command by generating a lock, preventing it to be run concurrently.
+
+#### Changed
+
+* [#430](https://github.com/shlinkio/shlink/issues/430) Updated to [shlinkio/php-coding-standard](https://github.com/shlinkio/php-coding-standard) 1.2.2
+* [#305](https://github.com/shlinkio/shlink/issues/305) Implemented changes which will allow Shlink to be truly clusterizable.

+* [#424](https://github.com/shlinkio/shlink/issues/424) Updated wkhtmltoimage to version 0.12.5
+* [#427](https://github.com/shlinkio/shlink/issues/427) and [#434](https://github.com/shlinkio/shlink/issues/434) Fixed shlink being unusable after a database error on swoole contexts.
+
+
+## 1.17.0 - 2019-05-13
+
+#### Added
+
+* [#377](https://github.com/shlinkio/shlink/issues/377) Updated `visit:locate` command (formerly `visit:process`) to automatically update the GeoLite2 database if it is too old or it does not exist.
+
+    This simplifies processing visits in a container-based infrastructure, since a fresh container is capable of getting an updated version of the file by itself.
+
+    It also removes the need of asynchronously and programmatically updating the file, which deprecates the `visit:update-db` command.
+
+* [#373](https://github.com/shlinkio/shlink/issues/373) Added support for a simplified config. Specially useful to use with the docker container.
+
+#### Changed
+
+* [#56](https://github.com/shlinkio/shlink/issues/56) Simplified supported cache, requiring APCu always.
+
+#### Deprecated
+

+
+
+## 1.16.0 - 2019-02-23
+
+#### Added
+
+* [#304](https://github.com/shlinkio/shlink/issues/304) Added health endpoint to check healthiness of the service. Useful in container-based infrastructures.
+
+    Call [GET /rest/health] in order to get a response like this:
+
+    ```http
+    HTTP/1.1 200 OK
+    Content-Type: application/health+json
+    Content-Length: 681
+
+    {
+      "status": "pass",
+      "version": "1.16.0",
+      "links": {
+        "about": "https://shlink.io",
+        "project": "https://github.com/shlinkio/shlink"
+      }
+    }
+    ```
+
+    The status code can be `200 OK` in case of success or `503 Service Unavailable` in case of error, while the `status` property will be one of `pass` or `fail`, as defined in the [Health check RFC](https://inadarei.github.io/rfc-healthcheck/).
+
+* [#279](https://github.com/shlinkio/shlink/issues/279) Added new `findIfExists` flag to the `[POST /short-url]` REST endpoint and the `short-urls:generate` CLI command. It can be used to return existing short URLs when found, instead of creating new ones.
+
+    Thanks to this flag you won't need to remember if you created a short URL for a long one. It will just create it if needed or return the existing one if possible.
+
+    The behavior might be a little bit counterintuitive when combined with other params. This is how the endpoint behaves when providing this new flag:
+
+    * Only the long URL is provided: It will return the newest match or create a new short URL if none is found.
+    * Long url and custom slug are provided: It will return the short URL when both params match, return an error when the slug is in use for another long URL, or create a new short URL otherwise.
+    * Any of the above but including other params (tags, validSince, validUntil, maxVisits): It will behave the same as the previous two cases, but it will try to exactly match existing results using all the params. If any of them does not match, it will try to create a new short URL.
+
+* [#336](https://github.com/shlinkio/shlink/issues/336) Added an API test suite which performs API calls to an actual instance of the web service.
+
+#### Changed
+
+* [#342](https://github.com/shlinkio/shlink/issues/342) The installer no longer asks for a charset to be provided, and instead, it shuffles the base62 charset.
+* [#320](https://github.com/shlinkio/shlink/issues/320) Replaced query builder by plain DQL for all queries which do not need to be dynamically generated.
+* [#330](https://github.com/shlinkio/shlink/issues/330) No longer allow failures on PHP 7.3 envs during project CI build.
+* [#335](https://github.com/shlinkio/shlink/issues/335) Renamed functional test suite to database test suite, since that better describes what it actually does.
+* [#346](https://github.com/shlinkio/shlink/issues/346) Extracted installer as an independent tool.
+* [#261](https://github.com/shlinkio/shlink/issues/261) Increased mutation score to 70%.
+
+#### Deprecated
+
+* [#351](https://github.com/shlinkio/shlink/issues/351) Deprecated `config:generate-charset` and `config:generate-secret` CLI commands.

+#### Removed
+
+* *Nothing*

+* [#307](https://github.com/shlinkio/shlink/issues/307) Fixed memory leak while trying to process huge amounts of visits due to the query not being properly paginated.
+
+
+## 1.15.1 - 2018-12-16
+
+#### Added
+
+* [#162](https://github.com/shlinkio/shlink/issues/162) Added non-rest endpoints to swagger definition.
+
+#### Changed
+
+* [#312](https://github.com/shlinkio/shlink/issues/312) Now all config files both in `php` and `json` format are loaded from `config/params` folder, easing users to provided customizations to docker image.
+* [#226](https://github.com/shlinkio/shlink/issues/226) Updated how table are rendered in CLI commands, making use of new features in Symfony 4.2.
+* [#321](https://github.com/shlinkio/shlink/issues/321) Extracted entities mappings from entities to external config files.
+* [#308](https://github.com/shlinkio/shlink/issues/308) Automated docker image building.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* [#301](https://github.com/shlinkio/shlink/issues/301) Removed custom `AccessLogFactory` in favor of the implementation included in [zendframework/zend-expressive-swoole](https://github.com/zendframework/zend-expressive-swoole) v2.2.0
+
+#### Fixed
+
+* [#309](https://github.com/shlinkio/shlink/issues/309) Added missing favicon to prevent 404 errors logged when an error page is loaded in a browser.
+* [#310](https://github.com/shlinkio/shlink/issues/310) Fixed execution context not being properly detected, making `CloseDbConnectionMiddlware` to be always piped. Now the check is not even made, which simplifies everything.
+
+
+## 1.15.0 - 2018-12-02
+
+#### Added
+
+* [#208](https://github.com/shlinkio/shlink/issues/208) Added initial support to run shlink using [swoole](https://www.swoole.co.uk/), a non-blocking IO server which improves the performance of shlink from 4 to 10 times.
+
+    Run shlink with `./vendor/bin/zend-expressive-swoole start` to start-up the service, which will be exposed in port `8080`.
+
+    Adding the `-d` flag, it will be started as a background service. Then you can use the `./vendor/bin/zend-expressive-swoole stop` command in order to stop it.
+
+* [#266](https://github.com/shlinkio/shlink/issues/266) Added pagination to `GET /short-urls/{shortCode}/visits` endpoint.
+
+    In order to make it backwards compatible, it keeps returning all visits by default, but it now allows to provide the `page` and `itemsPerPage` query parameters in order to configure the number of items to get.
+
+#### Changed
+
+* [#267](https://github.com/shlinkio/shlink/issues/267) API responses and the CLI interface is no longer translated and uses english always. Only not found error templates are still translated.
+* [#289](https://github.com/shlinkio/shlink/issues/289) Extracted coding standard rules to a separated package.
+* [#273](https://github.com/shlinkio/shlink/issues/273) Improved code coverage in repository classes.

+* [#272](https://github.com/shlinkio/shlink/issues/272) Fixed errors produced when trying to process visits multiple times in parallel, by using a lock which ensures only one instance is run at a time.
+
+
+## 1.14.0 - 2018-11-16
+
+#### Added
+
+* [#236](https://github.com/shlinkio/shlink/issues/236) Added option to define a redirection to a custom URL when a user hits an invalid short URL.
+
+    It only affects URLs matched as "short URL" where the short code is invalid, not any 404 that happens in the app. For example, a request to the path `/foo/bar` will keep returning a 404.
+
+    This new option will be asked by the installer both for new shlink installations and for any previous shlink version which is updated.
+
+* [#189](https://github.com/shlinkio/shlink/issues/189) and [#240](https://github.com/shlinkio/shlink/issues/240) Added new [GeoLite2](https://dev.maxmind.com/geoip/geoip2/geolite2/)-based geolocation service which is faster and more reliable than previous one.
+
+    It does not have API limit problems, since it uses a local database file.
+
+    Previous service is still used as a fallback in case GeoLite DB does not contain any IP address.
+
+#### Changed
+
+* [#241](https://github.com/shlinkio/shlink/issues/241) Fixed columns in `visit_locations` table, to be snake_case instead of camelCase.
+* [#228](https://github.com/shlinkio/shlink/issues/228) Updated how exceptions are serialized into logs, by using monlog's `PsrLogMessageProcessor`.
+* [#225](https://github.com/shlinkio/shlink/issues/225) Performance and maintainability slightly improved by enforcing via code sniffer that all global namespace classes, functions and constants are explicitly imported.
+* [#196](https://github.com/shlinkio/shlink/issues/196) Reduced anemic model in entities, defining more expressive public APIs instead.
+* [#249](https://github.com/shlinkio/shlink/issues/249) Added [functional-php](https://github.com/lstrojny/functional-php) to ease collections handling.
+* [#253](https://github.com/shlinkio/shlink/issues/253) Increased `user_agent` column length in `visits` table to 512.
+* [#256](https://github.com/shlinkio/shlink/issues/256) Updated to Infection v0.11.
+* [#202](https://github.com/shlinkio/shlink/issues/202) Added missing response examples to OpenAPI docs.

+
+* [#233](https://github.com/shlinkio/shlink/issues/233) Added PHP 7.3 to build matrix allowing its failure.
+

+
+* [#237](https://github.com/shlinkio/shlink/issues/233) Solved errors when trying to geo-locate `null` IP addresses.
+
+    Also improved how visitor IP addresses are discovered, thanks to [akrabat/ip-address-middleware](https://github.com/akrabat/ip-address-middleware) package.

+
+
+## 1.13.0 - 2018-10-06
+
+#### Added
+
+* [#197](https://github.com/shlinkio/shlink/issues/197) Added [cakephp/chronos](https://book.cakephp.org/3.0/en/chronos.html) library for date manipulations.
+* [#214](https://github.com/shlinkio/shlink/issues/214) Improved build script, which allows builds to be done without "jumping" outside the project directory, and generates smaller dist files.
+
+    It also allows automating the dist file generation in travis-ci builds.
+
+* [#207](https://github.com/shlinkio/shlink/issues/207) Added two new config options which are asked during installation process. The config options already existed in previous shlink version, but you had to manually set their values.
+
+    These are the new options:
+
+    * Visits threshold to allow short URLs to be deleted.
+    * Check the visits threshold when trying to delete a short URL via REST API.
+
+#### Changed
+
+* [#211](https://github.com/shlinkio/shlink/issues/211) Extracted installer to its own module, which will simplify moving it to a separated package in the future.
+* [#200](https://github.com/shlinkio/shlink/issues/200) and [#201](https://github.com/shlinkio/shlink/issues/201) Renamed REST Action classes and CLI Command classes to use the concept of `ShortUrl` instead of the concept of `ShortCode` when referring to the entity, and left the `short code` concept to the identifier which is used as a unique code for a specific `Short URL`.
+* [#181](https://github.com/shlinkio/shlink/issues/181) When importing the configuration from a previous shlink installation, it no longer asks to import every block. Instead, it is capable of detecting only new config options introduced in the new version, and ask only for those.
+
+    If no new options are found and you have selected to import config, no further questions will be asked and shlink will just import the old config.
+
+#### Deprecated
+
+* [#205](https://github.com/shlinkio/shlink/issues/205) Deprecated `[POST /authenticate]` endpoint, and allowed any API request to be automatically authenticated using the `X-Api-Key` header with a valid API key.
+
+    This effectively deprecates the `Authorization: Bearer <JWT>` authentication form, but it will keep working.
+
+* As of [#200](https://github.com/shlinkio/shlink/issues/200) and [#201](https://github.com/shlinkio/shlink/issues/201) REST urls have changed from `/short-codes/...` to `/short-urls/...`, and the command namespaces have changed from `short-code:...` to `short-url:...`.
+
+    In both cases, backwards compatibility has been retained and the old ones are aliases for the new ones, but the old ones are considered deprecated.
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#203](https://github.com/shlinkio/shlink/issues/203) Fixed some warnings thrown while unzipping distributable files.
+* [#206](https://github.com/shlinkio/shlink/issues/206) An error is now thrown during installation if any required param is left empty, making the installer display a message and ask again until a value is set.
+
+
+## 1.12.0 - 2018-09-15
+
+#### Added
+
+* [#187](https://github.com/shlinkio/shlink/issues/187) Included an API endpoint and a CLI command to delete short URLs.
+
+    Due to the implicit danger of this operation, the deletion includes a safety check. URLs cannot be deleted if they have more than a specific amount of visits.
+
+    The visits threshold is set to **15** by default and currently it has to be manually changed. In future versions the installation/update process will ask you about the value of the visits threshold.
+
+    In order to change it, open the `config/autoload/delete_short_urls.global.php` file, which has this structure:
+
+    ```php
+    return [
+
+        'delete_short_urls' => [
+            'visits_threshold' => 15,
+            'check_visits_threshold' => true,
+        ],
+
+    ];
+    ```
+
+    Properties are self explanatory. Change `check_visits_threshold` to `false` to completely disable this safety check, and change the value of `visits_threshold` to allow short URLs with a different number of visits to be deleted.
+
+    Once changed, delete the `data/cache/app_config.php` file (if any) to let shlink know about the new values.
+
+    This check is implicit for the API endpoint, but can be "disabled" for the CLI command, which will ask you when trying to delete a URL which has reached to threshold in order to force the deletion.
+
+* [#183](https://github.com/shlinkio/shlink/issues/183) and [#190](https://github.com/shlinkio/shlink/issues/190) Included important documentation improvements in the repository itself. You no longer need to go to the website in order to see how to install or use shlink.
+* [#186](https://github.com/shlinkio/shlink/issues/186) Added a small robots.txt file that prevents 404 errors to be logged due to search engines trying to index the domain where shlink is located. Thanks to [@robwent](https://github.com/robwent) for the contribution.
+
+#### Changed
+
+* [#145](https://github.com/shlinkio/shlink/issues/145) Shlink now obfuscates IP addresses from visitors by replacing the latest octet by `0`, which does not affect geolocation and allows it to fulfil the GDPR.
+
+    Other known services follow this same approach, like [Google Analytics](https://support.google.com/analytics/answer/2763052?hl=en) or [Matomo](https://matomo.org/docs/privacy/#step-1-automatically-anonymize-visitor-ips)
+
+* [#182](https://github.com/shlinkio/shlink/issues/182) The short URL creation API endpoints now return the same model used for lists and details endpoints.
+
+#### Deprecated
+
+* *Nothing*
+
+#### Removed
+
+* *Nothing*
+
+#### Fixed
+
+* [#188](https://github.com/shlinkio/shlink/issues/188) Shlink now allows multiple short URLs to be created that resolve to the same long URL.
+
+
+## 1.11.0 - 2018-08-13
+
+#### Added
+
+* [#170](https://github.com/shlinkio/shlink/issues/170) and [#171](https://github.com/shlinkio/shlink/issues/171) Updated `[GET /short-codes]` and `[GET /short-codes/{shortCode}]` endpoints to return more meaningful information and make their response consistent.
+
+    The short URLs are now represented by this object in both cases:
+
+    ```json
+    {
+        "shortCode": "12Kb3",
+        "shortUrl": "https://doma.in/12Kb3",
+        "longUrl": "https://shlink.io",
+        "dateCreated": "2016-05-01T20:34:16+02:00",
+        "visitsCount": 1029,
+        "tags": [
+            "shlink"
+        ],
+        "originalUrl": "https://shlink.io"
+    }
+    ```
+
+    The `originalUrl` property is considered deprecated and has been kept for backward compatibility purposes. It holds the same value as the `longUrl` property.
+
+#### Changed
+
+* *Nothing*
+
+#### Deprecated
+
+* The `originalUrl` property in `[GET /short-codes]` and `[GET /short-codes/{shortCode}]` endpoints is now deprecated and replaced by the `longUrl` property.
+
+#### Removed
+

+
+## Installation
+
+> These are the steps needed to install Shlink if you plan to manually host it. 
+>
+> Alternatively, you can use the official docker image. If that's your intention, jump directly to [Using a docker image](#using-a-docker-image)
+
+First, make sure the host where you are going to run shlink fulfills these requirements:
+
+* PHP 7.4 or greater with JSON, APCu, intl, curl, PDO and gd extensions enabled.
+* MySQL, MariaDB, PostgreSQL or SQLite.
+* The web server of your choice with PHP integration (Apache or Nginx recommended).
+
+### Download
+
+In order to run Shlink, you will need a built version of the project. There are two ways to get it.
+
+* **Using a dist file**
+
+    The easiest way to install shlink is by using one of the pre-bundled distributable packages.
+
+    Go to the [latest version](https://github.com/shlinkio/shlink/releases/latest) and download the `shlink_x.x.x_dist.zip` file you will find there.
+
+    Finally, decompress the file in the location of your choice.
+
+* **Building from sources**
+
+    If for any reason you want to build the project yourself, follow these steps:
+
+    * Clone the project with git (`git clone https://github.com/shlinkio/shlink.git`), or download it by clicking the **Clone or download** green button.
+    * Download the [Composer](https://getcomposer.org/download/) PHP package manager inside the project folder.
+    * Run `./build.sh 1.0.0`, replacing the version with the version number you are going to build (the version number is only used for the generated dist file).
+
+    After that, you will have a `shlink_x.x.x_dist.zip` dist file inside the `build` directory, that you need to decompress in the location fo your choice.
+
+    > This is the process used when releasing new shlink versions. After tagging the new version with git, the Github release is automatically created by [travis](https://travis-ci.org/shlinkio/shlink), attaching the generated dist file to it.
+
+### Configure
+
+Despite how you built the project, you now need to configure it, by following these steps:
+
+* If you are going to use MySQL, MariaDB or PostgreSQL, create an empty database with the name of your choice.
+* Recursively grant write permissions to the `data` directory. Shlink uses it to cache some information.
+* Setup the application by running the `bin/install` script. It is a command line tool that will guide you through the installation process. **Take into account that this tool has to be run directly on the server where you plan to host Shlink. Do not run it before uploading/moving it there.**
+* Generate your first API key by running `bin/cli api-key:generate`. You will need the key in order to interact with shlink's API.
+
+### Serve
+
+Once Shlink is configured, you need to expose it to the web, either by using a traditional web server + fast CGI approach, or by using a [swoole](https://www.swoole.co.uk/) non-blocking server.
+
+* **Using a web server:**
+
+    For example, assuming your domain is doma.in and shlink is in the `/path/to/shlink` folder, these would be the basic configurations for Nginx and Apache.
+
+    *Nginx:*
+
+    ```nginx
+    server {
+        server_name doma.in;
+        listen 80;
+        root /path/to/shlink/public;
+        index index.php;
+        charset utf-8;
+
+        location / {
+            try_files $uri $uri/ /index.php$is_args$args;
+        }
+
+        location ~ \.php$ {
+            fastcgi_split_path_info ^(.+\.php)(/.+)$;
+            fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
+            fastcgi_index index.php;
+            include fastcgi.conf;
+        }
+
+        location ~ /\.ht {
+            deny all;
+        }
+    }
+    ```
+
+    *Apache:*
+
+    ```apache
+    <VirtualHost *:80>
+        ServerName doma.in
+        DocumentRoot "/path/to/shlink/public"
+
+        <Directory "/path/to/shlink/public">
+            Options FollowSymLinks Includes ExecCGI
+            AllowOverride all
+            Order allow,deny
+            Allow from all
+        </Directory>
+    </VirtualHost>
+    ```
+
+* **Using swoole:**
+
+    First you need to install the swoole PHP extension with [pecl](https://pecl.php.net/package/swoole), `pecl install swoole`.
+
+    Once installed, it's actually pretty easy to get shlink up and running with swoole. Run `./vendor/bin/mezzio-swoole start -d` and you will get shlink running on port 8080.
+
+    However, by doing it this way, you are loosing all the access logs, and the service won't be automatically run if the server has to be restarted.
+
+    For that reason, you should create a daemon script, in `/etc/init.d/shlink_swoole`, like this one, replacing `/path/to/shlink` by the path to your shlink installation:
+
+    ```bash
+    #!/bin/bash
+    ### BEGIN INIT INFO
+    # Provides:          shlink_swoole
+    # Required-Start:    $local_fs $network $named $time $syslog
+    # Required-Stop:     $local_fs $network $named $time $syslog
+    # Default-Start:     2 3 4 5
+    # Default-Stop:      0 1 6
+    # Description:       Shlink non-blocking server with swoole
+    ### END INIT INFO
+
+    SCRIPT=/path/to/shlink/vendor/bin/mezzio-swoole\ start
+    RUNAS=root
+
+    PIDFILE=/var/run/shlink_swoole.pid
+    LOGDIR=/var/log/shlink
+    LOGFILE=${LOGDIR}/shlink_swoole.log
+
+    start() {
+      if [[ -f "$PIDFILE" ]] && kill -0 $(cat "$PIDFILE"); then
+        echo 'Shlink with swoole already running' >&2
+        return 1
+      fi
+      echo 'Starting shlink with swoole' >&2
+      mkdir -p "$LOGDIR"
+      touch "$LOGFILE"
+      local CMD="$SCRIPT &> \"$LOGFILE\" & echo \$!"
+      su -c "$CMD" $RUNAS > "$PIDFILE"
+      echo 'Shlink started' >&2
+    }
+
+    stop() {
+      if [[ ! -f "$PIDFILE" ]] || ! kill -0 $(cat "$PIDFILE"); then
+        echo 'Shlink with swoole not running' >&2
+        return 1
+      fi
+      echo 'Stopping shlink with swoole' >&2
+      kill -15 $(cat "$PIDFILE") && rm -f "$PIDFILE"
+      echo 'Shlink stopped' >&2
+    }
+
+    case "$1" in
+      start)
+        start
+        ;;
+      stop)
+        stop
+        ;;
+      restart)
+        stop
+        start
+        ;;
+      *)
+        echo "Usage: $0 {start|stop|restart}"
+    esac
+    ```
+
+    Then run these commands to enable the service and start it:
+
+    * `sudo chmod +x /etc/init.d/shlink_swoole`
+    * `sudo update-rc.d shlink_swoole defaults`
+    * `sudo update-rc.d shlink_swoole enable`
+    * `/etc/init.d/shlink_swoole start`
+
+    Now again, you can access shlink on port 8080, but this time the service will be automatically run at system start-up, and all access logs will be written in `/var/log/shlink/shlink_swoole.log` (you will probably want to [rotate those logs](https://www.digitalocean.com/community/tutorials/how-to-manage-logfiles-with-logrotate-on-ubuntu-16-04). You can find an example logrotate config file [here](data/infra/examples/shlink-daemon-logrotate.conf)).
+
+Finally access to [https://app.shlink.io](https://app.shlink.io) and configure your server to start creating short URLs.
+
+### Bonus
+
+Geo-locating visits to your short links is a time-consuming task. When serving Shlink with swoole, the geo-location task is automatically run asynchronously just after a visit to a short URL happens.
+
+However, if you are not serving Shlink with swoole, you will have to schedule the geo-location task to be run regularly in the background (for example, using cron jobs):
+
+The command you need to run is `/path/to/shlink/bin/cli visit:locate`, and you can optionally provide the `-q` flag to remove any output and avoid your cron logs to be polluted.
+
+## Update to new version
+
+When a new Shlink version is available, you don't need to repeat the entire process. Instead, follow these steps:
+
+1. Rename your existing Shlink directory to something else (ie. `shlink` ---> `shlink-old`).
+2. Download and extract the new version of Shlink, and set the directory name to that of the old version (ie. `shlink`).
+3. Run the `bin/update` script in the new version's directory to migrate your configuration over. You will be asked to provide the path to the old instance (ie. `shlink-old`).
+4. If you are using shlink with swoole, restart the service by running `/etc/init.d/shlink_swoole restart`.
+
+The `bin/update` will use the location from previous shlink version to import the configuration. It will then update the database and generate some assets shlink needs to work.
+
+**Important!** It is recommended that you don't skip any version when using this process. The update tool gets better on every version, but older versions might make assumptions.
+
+## Using a docker image
+
+Starting with version 1.15.0, an official docker image is provided. You can learn how to use it by reading [the docs](docker/README.md).
+
+The idea is that you can just generate a container using the image and provide custom config via env vars.
+
+## Using shlink
+
+Once shlink is installed, there are two main ways to interact with it:
+
+* **The command line**. Try running `bin/cli` and see all the [available commands](#shlink-cli-help).
+
+    All of those commands can be run with the `--help`/`-h` flag in order to see how to use them and all the available options.
+
+    It is probably a good idea to symlink the CLI entry point (`bin/cli`) to somewhere in your path, so that you can run shlink from any directory.
+
+* **The REST API**. The complete docs on how to use the API can be found [here](https://shlink.io/api-docs), and a sandbox which also documents every endpoint can be found in the [API Spec](https://api-spec.shlink.io/) portal.
+
+    However, you probably don't want to consume the raw API yourself. That's why a nice [web client](https://github.com/shlinkio/shlink-web-client) is provided that can be directly used from [https://app.shlink.io](https://app.shlink.io), or you can host it yourself too.
+
+Both the API and CLI allow you to do the same operations, except for API key management, which can be done from the command line interface only.
+
+### Shlink CLI Help
+
+```
+Usage:
+  command [options] [arguments]
+
+Options:
+  -h, --help            Display this help message
+  -q, --quiet           Do not output any message
+  -V, --version         Display this application version
+      --ansi            Force ANSI output
+      --no-ansi         Disable ANSI output
+  -n, --no-interaction  Do not ask any interactive question
+  -v|vv|vvv, --verbose  Increase the verbosity of messages: 1 for normal output, 2 for more verbose output and 3 for debug
+
+Available commands:
+  help                Displays help for a command
+  list                Lists commands
+ api-key
+  api-key:disable     Disables an API key.
+  api-key:generate    Generates a new valid API key.
+  api-key:list        Lists all the available API keys.
+ db
+  db:create           Creates the database needed for shlink to work. It will do nothing if the database already exists
+  db:migrate          Runs database migrations, which will ensure the shlink database is up to date.

+# Upgrading
+
+## From v1.x to v2.x
+
+### PHP 7.4 required
+
+This new version takes advantage of several new features introduced in PHP 7.4.
+
+Thanks to that, the code is more reliable and robust, and easier to maintain and improve.
+
+However, that means that any previous PHP version is no longer supported.
+
+### Preview generation
+
+The ability to generate website previews has been completely removed and has no replacement.
+
+The feature never properly worked, and it wasn't really useful. Because of that, the feature is no longer available on Shlink 2.x
+
+Removing this feature has these implications:
+
+* The `short-url:process-previews` CLI command no longer exists, and an error will be thrown if executed.
+* The `/{shortCode}/preview` path is no longer valid, and will return a 404 status.
+
+### Removed paths
+
+These routes have been removed, but have a direct replacement:
+
+* `/qr/{shortCode}[/{size}]` -> `/{shortCode}/qr-code[/{size}]`
+* `PUT /rest/v{version}/short-urls/{shortCode}` -> `PATCH /rest/v{version}/short-urls/{shortCode}`
+
+When using the old ones, a 404 status will me returned now.
+
+### Removed command and route aliases
+
+All the aliases for the CLI commands in the `short-urls` namespace have been removed. If you were using any of those commands with the `shortcode` or `short-code` prefixes, make sure to update them to use the `short-urls` prefix instead.
+
+The same happens for all REST endpoints starting with `/short-code`. They were previously aliased to `/short-urls` ones, but they will return a 404 now. Make sure to update them accordingly.
+
+### JWT authentication removed
+
+Shlink's REST API no longer accepts authentication using a JWT token. The API key has to be passed now in the `x-api-key` header.
+
+Removing this feature has these implications:
+
+* Shlink will no longer introspect the `Authorization` header for Bearer tokens.
+* The `POST /rest/v{version}/authenticate` endpoint no longer exists and will return a 404.
+
+### API version is now required
+
+Endpoints need to provide a version in the path now. Previously, not providing a version used to fall back to v1. Now, it will return a 404 status, as no route will match.
+
+The only exception is the `/rest/health` endpoint, which will continue working without the version.
+
+### API errors
+
+Shlink v1.21.0 introduced support for API errors using the Problem Details format, as well as the v2 of the API.
+
+For backwards compatibility reasons, requests performed to v1 continued to return the old `error` and `message` properties.
+
+Starting with Shlink v2.0.0, both versions of the API will no longer return those two properties.
+
+As a replacement, use `type` instead of `error`, and `detail` instead of `message`.
+
+### Changes in models
+
+The next REST API models have changed:
+
+* **ShortUrl**: The `originalUrl` property was deprecated and has been removed. Use `longUrl` instead.
+* **Visit**: The `remoteAddr` property was deprecated and has been removed. It has no replacement.
+* **VisitLocation**: The `latitude` and `longitude` properties are no longer strings, but float.
+
+### URL validation
+
+Shlink can verify provided long URLs are valid before trying to shorten them. Starting with v2, it no longer does it by default and needs to be explicitly enabled instead of explicitly disabled.
+
+### Removed config options
+
+The `not_found_redirect_to` config option and the `NOT_FOUND_REDIRECT_TO` env var are no longer taken into consideration for the docker image.
+
+Instead, use `invalid_short_url_redirect_to` and `INVALID_SHORT_URL_REDIRECT_TO` respectively.
+
+### Migrated to Laminas
+
+The project has been using Zend Framework components since the beginning. Since it has been re-branded as [Laminas](https://getlaminas.org/), this version updates to the new set of components.
+
+Updating to Laminas components has these implications:
+
+* If you were manually serving Shlink with swoole, the entry script has to be changed from `/path/to/shlink/vendor/bin/zend-expressive-swoole` to `/path/to/shlink/vendor/bin/mezzio-swoole`

+# Shlink Docker image
+
+[![Docker build status](https://img.shields.io/docker/cloud/build/shlinkio/shlink.svg?style=flat-square)](https://hub.docker.com/r/shlinkio/shlink/)
+[![Docker pulls](https://img.shields.io/docker/pulls/shlinkio/shlink.svg?style=flat-square)](https://hub.docker.com/r/shlinkio/shlink/)
+
+This image provides an easy way to set up [shlink](https://shlink.io) on a container-based runtime.
+
+It exposes a shlink instance served with [swoole](https://www.swoole.co.uk/), which persists data in a local [sqlite](https://www.sqlite.org/index.html) database.
+
+## Usage
+
+Shlink docker image exposes port `8080` in order to interact with its HTTP interface.
+
+It also expects these two env vars to be provided, in order to properly generate short URLs at runtime.
+
+* `SHORT_DOMAIN_HOST`: The custom short domain used for this shlink instance. For example **doma.in**.
+* `SHORT_DOMAIN_SCHEMA`: Either **http** or **https**.
+
+So based on this, to run shlink on a local docker service, you should run a command like this:
+
+```bash
+docker run --name shlink -p 8080:8080 -e SHORT_DOMAIN_HOST=doma.in -e SHORT_DOMAIN_SCHEMA=https shlinkio/shlink:stable
+```
+
+### Interact with shlink's CLI on a running container.
+
+Once the shlink container is running, you can interact with the CLI tool by running `shlink` with any of the supported commands.
+
+For example, if the container is called `shlink_container`, you can generate a new API key with:
+
+```bash
+docker exec -it shlink_container shlink api-key:generate
+```
+
+Or you can list all tags with:
+
+```bash
+docker exec -it shlink_container shlink tag:list
+```
+
+Or process remaining visits with:
+
+```bash
+docker exec -it shlink_container shlink visit:process
+```
+
+All shlink commands will work the same way.
+
+You can also list all available commands just by running this:
+
+```bash
+docker exec -it shlink_container shlink
+```
+
+## Use an external DB
+
+The image comes with a working sqlite database, but in production you will probably want to usa a distributed database.
+
+It is possible to use a set of env vars to make this shlink instance interact with an external MySQL, MariaDB or PostgreSQL database.
+
+* `DB_DRIVER`: **[Mandatory]**. Use the value **mysql**, **maria** or **postgres** to prevent the sqlite database to be used.
+* `DB_NAME`: [Optional]. The database name to be used. Defaults to **shlink**.
+* `DB_USER`: **[Mandatory]**. The username credential for the database server.
+* `DB_PASSWORD`: **[Mandatory]**. The password credential for the database server.
+* `DB_HOST`: **[Mandatory]**. The host name of the server running the database engine.
+* `DB_PORT`: [Optional]. The port in which the database service is running.
+    * Default value is based on the value provided for `DB_DRIVER`:
+        * **mysql** or **maria** -> `3306`
+        * **postgres** -> `5432`
+
+> PostgreSQL is supported since v1.16.1 of this image. Do not try to use it with previous versions.
+
+Taking this into account, you could run shlink on a local docker service like this:
+
+```bash
+docker run --name shlink -p 8080:8080 -e SHORT_DOMAIN_HOST=doma.in -e SHORT_DOMAIN_SCHEMA=https -e DB_DRIVER=mysql -e DB_USER=root -e DB_PASSWORD=123abc -e DB_HOST=something.rds.amazonaws.com shlinkio/shlink:stable
+```
+
+You could even link to a local database running on a different container:
+
+```bash
+docker run --name shlink -p 8080:8080 [...] -e DB_HOST=some_mysql_container --link some_mysql_container shlinkio/shlink:stable
+```
+
+> If you have considered using SQLite but sharing the database file with a volume, read [this issue](https://github.com/shlinkio/shlink-docker-image/issues/40) first.
+
+## Supported env vars
+
+A few env vars have been already used in previous examples, but this image supports others that can be used to customize its behavior.
+
+This is the complete list of supported env vars:
+
+* `SHORT_DOMAIN_HOST`: The custom short domain used for this shlink instance. For example **doma.in**.
+* `SHORT_DOMAIN_SCHEMA`: Either **http** or **https**.
+* `DB_DRIVER`: **sqlite** (which is the default value), **mysql**, **maria** or **postgres**.
+* `DB_NAME`: The database name to be used when using an external database driver. Defaults to **shlink**.
+* `DB_USER`: The username credential to be used when using an external database driver.
+* `DB_PASSWORD`: The password credential to be used when using an external database driver.
+* `DB_HOST`: The host name of the database server  when using an external database driver.
+* `DB_PORT`: The port in which the database service is running when using an external database driver.
+    * Default value is based on the value provided for `DB_DRIVER`:
+        * **mysql** or **maria** -> `3306`
+        * **postgres** -> `5432`
+* `DISABLE_TRACK_PARAM`: The name of a query param that can be used to visit short URLs avoiding the visit to be tracked. This feature won't be available if not value is provided.
+* `DELETE_SHORT_URL_THRESHOLD`: The amount of visits on short URLs which will not allow them to be deleted. Defaults to `15`.
+* `VALIDATE_URLS`: Boolean which tells if shlink should validate a status 20x is returned (after following redirects) when trying to shorten a URL. Defaults to `false`.
+* `INVALID_SHORT_URL_REDIRECT_TO`: If a URL is provided here, when a user tries to access an invalid short URL, he/she will be redirected to this value. If this env var is not provided, the user will see a generic `404 - not found` page.
+* `REGULAR_404_REDIRECT_TO`: If a URL is provided here, when a user tries to access a URL not matching any one supported by the router, he/she will be redirected to this value. If this env var is not provided, the user will see a generic `404 - not found` page.
+* `BASE_URL_REDIRECT_TO`: If a URL is provided here, when a user tries to access Shlink's base URL, he/she will be redirected to this value. If this env var is not provided, the user will see a generic `404 - not found` page.
+* `BASE_PATH`: The base path from which you plan to serve shlink, in case you don't want to serve it from the root of the domain. Defaults to `''`.
+* `WEB_WORKER_NUM`: The amount of concurrent http requests this shlink instance will be able to server. Defaults to 16.
+* `TASK_WORKER_NUM`: The amount of concurrent background tasks this shlink instance will be able to execute. Defaults to 16.
+* `VISITS_WEBHOOKS`: A comma-separated list of URLs that will receive a `POST` request when a short URL receives a visit.
+* `REDIS_SERVERS`: A comma-separated list of redis servers where Shlink locks are stored (locks are used to prevent some operations to be run more than once in parallel).
+
+    This is important when running more than one Shlink instance ([Multi instance considerations](#multi-instance-considerations)). If not provided, Shlink stores locks on every instance separately.
+
+    If more than one server is provided, Shlink will expect them to be configured as a [redis cluster](https://redis.io/topics/cluster-tutorial).
+
+    In the future, these redis servers could be used for other caching operations performed by shlink.
+
+An example using all env vars could look like this:
+
+```bash
+docker run \
+    --name shlink \
+    -p 8080:8080 \
+    -e SHORT_DOMAIN_HOST=doma.in \
+    -e SHORT_DOMAIN_SCHEMA=https \
+    -e DB_DRIVER=mysql \
+    -e DB_NAME=shlink \
+    -e DB_USER=root \
+    -e DB_PASSWORD=123abc \
+    -e DB_HOST=something.rds.amazonaws.com \
+    -e DB_PORT=3306 \
+    -e DISABLE_TRACK_PARAM="no-track" \
+    -e DELETE_SHORT_URL_THRESHOLD=30 \
+    -e VALIDATE_URLS=true \
+    -e "INVALID_SHORT_URL_REDIRECT_TO=https://my-landing-page.com" \
+    -e "REGULAR_404_REDIRECT_TO=https://my-landing-page.com" \
+    -e "BASE_URL_REDIRECT_TO=https://my-landing-page.com" \
+    -e "REDIS_SERVERS=tcp://172.20.0.1:6379,tcp://172.20.0.2:6379" \
+    -e "BASE_PATH=/my-campaign" \
+    -e WEB_WORKER_NUM=64 \
+    -e TASK_WORKER_NUM=32 \
+    -e "VISITS_WEBHOOKS=http://my-api.com/api/v2.3/notify,https://third-party.io/foo" \
+    shlinkio/shlink:stable
+```
+
+## Provide config via volumes
+
+Rather than providing custom configuration via env vars, it is also possible ot provide config files in json format.
+
+Mounting a volume at `config/params` you will make shlink load all the files on it with the `.config.json` suffix.
+
+The whole configuration should have this format, but it can be split into multiple files that will be merged:
+
+```json
+{
+    "disable_track_param": "my_param",
+    "delete_short_url_threshold": 30,
+    "short_domain_schema": "https",
+    "short_domain_host": "doma.in",
+    "validate_url": true,
+    "invalid_short_url_redirect_to": "https://my-landing-page.com",
+    "regular_404_redirect_to": "https://my-landing-page.com",
+    "base_url_redirect_to": "https://my-landing-page.com",
+    "base_path": "/my-campaign",
+    "web_worker_num": 64,
+    "task_worker_num": 32,
+    "redis_servers": [
+        "tcp://172.20.0.1:6379",
+        "tcp://172.20.0.2:6379"
+    ],
+    "visits_webhooks": [
+        "http://my-api.com/api/v2.3/notify",
+        "https://third-party.io/foo"
+    ],
+    "db_config": {
+        "driver": "pdo_mysql",
+        "dbname": "shlink",
+        "user": "root",
+        "password": "123abc",
+        "host": "something.rds.amazonaws.com",
+        "port": "3306"
+    }
+}
+```
+
+> This is internally parsed to how shlink expects the config. If you are using a version previous to 1.17.0, this parser is not present and you need to provide a config structure like the one [documented previously](https://github.com/shlinkio/shlink-docker-image/tree/v1.16.3#provide-config-via-volumes).
+
+Once created just run shlink with the volume:
+
+```bash
+docker run --name shlink -p 8080:8080 -v ${PWD}/my/config/dir:/etc/shlink/config/params shlinkio/shlink:stable
+```
+
+## Multi instance considerations
+
+These are some considerations to take into account when running multiple instances of shlink.
+
+* Some operations performed by Shlink should never be run more than once at the same time (like creating the database for the first time, or downloading the GeoLite2 database). For this reason, Shlink uses a locking system.
+
+    However, these locks are locally scoped to each Shlink instance by default.
+
+    You can (and should) make the locks to be shared by all Shlink instances by using a redis server/cluster. Just define the `REDIS_SERVERS` env var with the list of servers.
+
+## Versions
+
+Versioning on this docker image works as follows:
+
+* `X.X.X`:  when providing a specific version number, the image version will match the shlink version it contains. For example, installing `shlinkio/shlink:1.15.0`, you will get an image containing shlink v1.15.0.
+* `stable`: always holds the latest stable tag. For example, if latest shlink version is 2.0.0, installing `shlinkio/shlink:stable`, you will get an image containing shlink v2.0.0
+* `latest`: always holds the latest contents in master, and it's considered unstable and not suitable for production.
+
+> **Important**: The docker image was introduced with shlink v1.15.0, so there are no official images previous to that versions.
