-# Contributing
-
-This file will guide you through the process of getting to project up and running, in case you want to provide coding contributions.
-
-You will also see how to ensure the code fulfills the expected code checks, and how to create a pull request.
-
-## System dependencies
-
-The project provides all its dependencies as docker containers through a docker-compose configuration.
-
-Because of this, the only actual dependencies are [docker](https://docs.docker.com/get-docker/) and [docker-compose](https://docs.docker.com/compose/install/).
-
-## Setting up the project
-
-The first thing you need to do is fork the repository, and clone it in your local machine.
-
-Then you will have to follow these steps:
-
-* Copy all files with `.local.php.dist` extension from `config/autoload` by removing the dist extension.
-
-    For example the `common.local.php.dist` file should be copied as `common.local.php`.
-
-* Copy the file `docker-compose.override.yml.dist` by also removing the `dist` extension.
-* Start-up the project by running `docker-compose up`.
-
-    The first time this command is run, it will create several containers that are used during development, so it may take some time.
-
-    It will also create some empty databases and install the project dependencies with composer.
-
-* Run `./indocker bin/cli db:create` to create the initial database.
-* Run `./indocker bin/cli db:migrate` to get database migrations up to date.
-* Run `./indocker bin/cli api-key:generate` to get your first API key generated.
-
-Once you finish this, you will have the project exposed in ports `8000` through nginx+php-fpm and `8080` through swoole.
-
-> Note: The `indocker` shell script is a helper used to run commands inside the main docker container.
-
-## Project structure
-
-This project is structured as a modular application, using [laminas/laminas-config-aggregator](https://github.com/laminas/laminas-config-aggregator) to merge the configuration provided by every module.
-
-All modules are inside the `module` folder, and each one has its own `src`, `test` and `config` folders, with the source code, tests and configuration. They also have their own `ConfigProvider` class, which is consumed by the config aggregator.
-
-This is a simplified version of the project structure:
-
-```
-shlink
-├── bin
-│   ├── cli
-│   ├── install
-│   └── update
-├── config
-│   ├── autoload
-│   ├── params
-│   ├── config.php
-│   └── container.php
-├── data
-│   ├── cache
-│   ├── locks
-│   ├── log
-│   ├── migrations
-│   └── proxies
-├── docs
-│   ├── async-api
-│   └── swagger
-├── module
-│   ├── CLI
-│   ├── Core
-│   └── Rest
-├── public
-├── composer.json
-└── README.md
-```
-
-The purposes of every folder are:
-
-* `bin`: It contains the CLI tools. The `cli` one is the main entry point to run shlink from the command line, while `install` and `update` are helper tools used to install and update shlink when not using the docker image.
-* `config`: Contains application-wide configurations, which are later merged with the ones provided by every module.
-* `data`: Common runtime-generated git-ignored assets, like logs, caches, etc.
-* `docs`: Any project documentation is stored here, like API spec definitions.
-* `module`: Contains a subfolder for every module in the project. Modules contain the source code, tests and configurations for every context in the project.
-* `public`: Few assets (like `favicon.ico` or `robots.txt`) and the web entry point are stored here. This web entry point is not used when serving the app with swoole.
-
-## Project tests
-
-In order to ensure stability and no regressions are introduced while developing new features, this project has different types of tests.
-
-* **Unit tests**: These are the simplest to run, and usually test individual pieces of code, replacing any external dependency by mocks.
-
-    The code coverage of unit tests is pretty high, and only entity repositories are excluded because of their nature.
-
-* **Database tests**: These are integration tests that run against a real database, and only cover entity repositories.
-
-    Its purpose is to verify all the database queries behave as expected and return what's expected.
-
-    The project provides some tooling to run them against any of the supported database engines.
-
-* **API tests**: These are E2E tests that spin up an instance of the app and test it from the outside, by interacting with the REST API.
-
-    These are the best tests to catch regressions, and to verify everything interacts as expected.
-
-    They use MySQL as the database engine, and include some fixtures that ensure the same data exists at the beginning of the execution.
-
-* **CLI tests**: *TBD. Once included, its purpose will be the same as API tests, but running through the command line*
-
-Depending on the kind of contribution, maybe not all kinds of tests are needed, but the more you provide, the better.
-
-## Running code checks
-
-* Run `./indocker composer cs` to check coding styles are fulfilled.
-* Run `./indocker composer cs:fix` to fix coding styles (some may not be fixable from the CLI)
-* Run `./indocker composer stan` to statically analyze the code with [phpstan](https://phpstan.org/). This tool is the closest to "compile" PHP and verify everything would work as expected.
-* Run `./indocker composer test:unit` to run the unit tests.
-* Run `./indocker composer test:db` to run the database integration tests.
-
-    This command runs the same test suite against all supported database engines. If you just want to run one of them, you can add one of `:sqlite`, `:mysql`, `:maria`, `:postgres`, `:mssql` at the end of the command.
-    
-    For example, `test:db:postgres`.
-
-* Run `./indocker composer test:api` to run API E2E tests. For these, the MySQL database engine is used.
-* Run `./indocker composer infect:test` ti run both unit and database tests (over sqlite) and then apply mutations to them with [infection](https://infection.github.io/).
-* Run `./indocker composer ci` to run all previous commands together. This command is run during the project's continuous integration.
-
-> Note: Due to some limitations in the tooling used by shlink, the testing databases need to exist beforehand, both for db and api tests (except sqlite).
->
-> However, they just need to be created empty, with no tables. Also, once created, they are automatically reset before every new execution.
->
-> The testing database is always called `shlink_test`. You can create it using the database client of your choice. [DBeaver](https://dbeaver.io/) is a good multi-platform desktop database client which supports all the engines supported by shlink.
-
-## Pull request process
-
-In order to provide pull requests to this project, you should always start by creating a new branch, where you will make all desired changes.
-
-The base branch should always be `develop`, and the target branch for the pull request should also be `develop`.
-
-Before your branch can be merged, all the checks described in [Running code checks](#running-code-checks) have to be passing. You can verify that manually by running `./indocker composer ci`, or wait for the build to be run automatically after the pull request is created.

 ### 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.
+Depending on the shlink version you installed and how you serve it, there are a couple of time-consuming tasks that shlink expects you to do manually, or at least it is recommended, since it will improve runtime performance.
 
-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):
+Those tasks can be performed using shlink's CLI tool, so it should be easy to schedule them to be run 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.
+* **For shlink older than 1.18.0 or not using swoole to serve it**: Resolve IP address locations: `/path/to/shlink/bin/cli visit:locate`
+
+    If you don't run this command regularly, the stats will say all visits come from *unknown* locations.
+
+    > If you serve Shlink with swoole and use v1.18.0 at least, visit location is automatically scheduled by Shlink just after the visit occurs, using swoole's task system.
+
+* **For shlink older than v1.17.0**: Update IP geolocation database: `/path/to/shlink/bin/cli visit:update-db`
+
+    When shlink is installed it downloads a fresh [GeoLite2](https://dev.maxmind.com/geoip/geoip2/geolite2/) db file. Running this command will update this file.
+
+    The file is updated the first Tuesday of every month, so it should be enough running this command the first Wednesday.
+
+    > You don't need this if you use Shlink v1.17.0 or newer, since now it downloads/updates the geolocation database automatically just before trying to use it.
+
+* Generate website previews: `/path/to/shlink/bin/cli short-url:process-previews`
+
+    Running this will improve the performance of the `doma.in/abc123/preview` URLs, which return a preview of the site.
+
+    > **Important!** Generating previews is considered deprecated and the feature will be removed in Shlink v2.

-## Multiple domains
-
-While in many cases you will just have one short domain and you'll want all your short URLs to be served from it, there are some cases in which you might want to have multiple short domains served from the same Shlink instance.
-
-If that's the case, you need to understand how Shlink will behave when managing your short URLs or any of them is visited.
-
-### Management
-
-When you create a short URL it is possible to optionally pass a `domain` param. If you don't pass it, the short URL will be created for the default domain (the one provided during Shlink's installation or in the `SHORT_DOMAIN_HOST` env var when using the docker image).
-
-However, if you pass it, the short URL will be "linked" to that domain.
-
-> Note that, if the default domain is passed, Shlink will ignore it and will behave as if no `domain` param was provided.
-
-The main benefit of being able to pass the domain is that Shlink will allow the same custom slug to be used in multiple short URLs, as long as the domain is different (like `example.com/my-compaign`, `another.com/my-compaign` and `foo.com/my-compaign`).
-
-Then, each short URL will be tracked separately and you will be able to define specific tags and metadata for each one of them.
-
-However, this has a side effect. When you try to interact with an existing short URL (editing tags, editing meta, resolving it or deleting it), either from the REST API or the CLI tool, you will have to provide the domain appropriately.
-
-Let's imagine this situation. Shlink's default domain is `example.com`, and you have the next short URLs:
-
-* `https://example.com/abc123` -> a regular short URL where no domain was provided.
-* `https://example.com/my-campaign` -> a regular short URL where no domain was provided, but it has a custom slug.
-* `https://another.com/my-campaign` -> a short URL where the `another.com` domain was provided, and it has a custom slug.
-* `https://another.com/def456` -> a short URL where the `another.com` domain was provided.
-
-These are some of the results you will get when trying to interact with them, depending on the params you provide:
-
-* Providing just the `abc123` short code -> the first URL will be matched.
-* Providing just the `my-campaign` short code -> the second URL will be matched, since you did not specify a domain, therefor, Shlink looks for the one with the short code/slug `my-campaign` which is also linked to default domain (or not linked to any domain, to be more accurate).
-* Providing the `my-campaign` short code and the `another.com` domain -> The third one will be matched.
-* Providing just the `def456` short code -> Shlink will fail/not find any short URL, since there's none with the short code `def456` linked to default domain.
-* Providing the `def456` short code and the `another.com` domain -> The fourth short URL will be matched.
-* Providing any short code and the `foo.com` domain -> Again, no short URL will be found, as there's none linked to `foo.com` domain.
-
-### Visits
-
-Before adding support for multiple domains, you could point as many domains as you wanted to Shlink, and they would have always worked for existing short codes/slugs.
-
-In order to keep backwards compatibility, Shlink's behavior when a short URL is visited is slightly different, getting to fallback in some cases.
-
-Let's continue with previous example, and also consider we have three domains that will resolve to our Shlink instance, which are `example.com`, `another.com` and `foo.com`.
-
-With that in mind, this is how Shlink will behave when the next short URLs are visited:
-
-* `https://another.com/abc123` -> There was no short URL specifically defined for domain `another.com` and short code `abc123`, but it exists for default domain (`example.com`), so it will fall back to it and redirect to where `example.com/abc123` is configured to redirect.
-* `https://example.com/def456` -> The fall-back does not happen from default domain to specific ones, only the other way around (like in previous case). Because of that, this one will result in a not-found URL, even though the `def456` short code exists for `another.com` domain.
-* `https://foo.com/abc123` -> This will also fall-back to `example.com/abc123`, like in the first case.
-* `https://another.com/non-existing` -> The combination of `another.com` domain with the `non-existing` slug does not exist, so Shlink will try to fall-back to the same but for default domain (`example.com`). However, since that combination does not exist either, it will result in a not-found URL.
-* Any other short URL visited exactly as it was configured will, of course, resolve as expected.
-
-### Special redirects
-
-It is currently possible to configure some special redirects when the base domain is visited, a URL does not match, or an invalid/disabled short URL is visited.
-
-Those are configured during Shlink's installation or via env vars when using the docker image.
-
-Currently those are all shared for all domains serving the same Shlink instance, but the plan is to update that and allow specific ones for every existing domain.

UPGRADE.md

-# 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`

-## Other integrations
-
-### Use an external redis server
-
-If you plan to run more than one Shlink instance, there are some resources that should be shared ([Multi instance considerations](#multi-instance-considerations)).
-
-One of those resources are the locks Shlink generates to prevent some operations to be run more than once in parallel (in the future, these redis servers could be used for other caching operations).
-
-In order to share those locks, you should use an external redis server (or a cluster of redis servers), by providing the `REDIS_SERVERS` env var.
-
-It can be either one server name or a comma-separated list of servers.
-
-> If more than one redis server is provided, Shlink will expect them to be configured as a [redis cluster](https://redis.io/topics/cluster-tutorial).
-
-### Integrate with a mercure hub server
-
-One way to get real time updates when certain events happen in Shlink is by integrating it with a [mercure hub](https://mercure.rocks/) server.
-
-If you do that, Shlink will publish updates and other clients can subscribe to those.
-
-There are three env vars you need to provide if you want to enable this:
-
-* `MERCURE_PUBLIC_HUB_URL`: **[Mandatory]**. The public URL of a mercure hub server to which Shlink will sent updates. This URL will also be served to consumers that want to subscribe to those updates.
-* `MERCURE_INTERNAL_HUB_URL`: **[Optional]**. An internal URL for a mercure hub. Will be used only when publishing updates to mercure, and does not need to be public. If this is not provided, the `MERCURE_PUBLIC_HUB_URL` one will be used to publish updates.
-* `MERCURE_JWT_SECRET`: **[Mandatory]**. The secret key that was provided to the mercure hub server, in order to be able to generate valid JWTs for publishing/subscribing to that server.
-
-So in order to run shlink with mercure integration, you would do it like this:
-
-```bash
-docker run \
-    --name shlink \
-    -p 8080:8080 \
-    -e SHORT_DOMAIN_HOST=doma.in \
-    -e SHORT_DOMAIN_SCHEMA=https \
-    -e "MERCURE_PUBLIC_HUB_URL=https://example.com"
-    -e "MERCURE_INTERNAL_HUB_URL=http://my-mercure-hub.prod.svc.cluster.local"
-    -e MERCURE_JWT_SECRET=super_secret_key
