+## Full documentation
 
-> 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)
+This document contains the very basics to get started with Shlink. If you want to learn everything you can do with it, visit the [full searchable documentation](https://shlink.io/documentation/).
+
+## 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](https://shlink.io/documentation/install-docker-image/).
+
+The idea is that you can just generate a container using the image and provide the custom config via env vars.
+
+## Self hosted
 
 First, make sure the host where you are going to run shlink fulfills these requirements:
 
-* PHP 7.4 or greater with JSON, curl, PDO, intl and gd extensions enabled.
+* PHP 8.0
+* The next PHP extensions: json, curl, pdo, intl, gd and gmp.
+    * apcu extension is recommended if you don't plan to use swoole.
+    * xml extension is required if you want to generate QR codes in svg format.
 * MySQL, MariaDB, PostgreSQL, Microsoft SQL Server or SQLite.
 * The web server of your choice with PHP integration (Apache or Nginx recommended).

 * 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/php7.4-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"
-

-            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

-      *)
-        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.

-## 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.

 # Shlink Docker image
 
-[![Docker pulls](https://img.shields.io/docker/pulls/shlinkio/shlink.svg?style=flat-square)](https://hub.docker.com/r/shlinkio/shlink/)
+[![Docker build status](https://img.shields.io/github/workflow/status/shlinkio/shlink/Build%20docker%20image?logo=docker&style=flat-square)](https://github.com/shlinkio/shlink/actions?query=workflow%3A%22Build+docker+image%22)
+[![Docker pulls](https://img.shields.io/docker/pulls/shlinkio/shlink.svg?logo=docker&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.
+It exposes a shlink instance served with [swoole](https://www.swoole.co.uk/), which can be linked to external databases to persist data.
 
 ## Usage
 
-Shlink docker image exposes port `8080` in order to interact with its HTTP interface.
+The most basic way to run Shlink's docker image is by providing these mandatory env vars.
 
-It also expects these two env vars to be provided, in order to properly generate short URLs at runtime.
+* `DEFAULT_DOMAIN`: The default short domain used for this shlink instance. For example **doma.in**.
+* `USE_HTTPS`: Either **true** or **false**.
+* `GEOLITE_LICENSE_KEY`: Your GeoLite2 license key. [Learn more](https://shlink.io/documentation/geolite-license-key/) about this.
 
-* `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 -e GEOLITE_LICENSE_KEY=kjh23ljkbndskj345 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 locate remaining visits with:
-
-```bash
-docker exec -it shlink_container shlink visit:locate
-```
-
-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, PostgreSQL or Microsoft SQL Server database.
-
-* `DB_DRIVER`: **[Mandatory]**. Use the value **mysql**, **maria**, **postgres** or **mssql** 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`
-        * **mssql** -> `1433`
-
-> PostgreSQL is supported since v1.16.1 and Microsoft SQL server since v2.1.0. Do not try to use them with previous versions.
-
-Taking this into account, you could run shlink on a local docker service like this:
+To run shlink on top of a local docker service, and using an internal SQLite database, do the following:
 
 ```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.
-
-## 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
-    shlinkio/shlink:stable
-```
-
-## All 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**, **postgres** or **mssql**.
-* `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`
-        * **mssql** -> `1433`
-* `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.
-* `DEFAULT_SHORT_CODES_LENGTH`: The length you want generated short codes to have. It defaults to 5 and has to be at least 4, so any value smaller than that will fall back to 4.
-* `GEOLITE_LICENSE_KEY`: The license key used to download new GeoLite2 database files. This is not mandatory, as a default license key is provided, but it is **strongly recommended** that you provide your own. Go to [https://shlink.io/documentation/geolite-license-key](https://shlink.io/documentation/geolite-license-key) to know how to generate it.
-* `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).
-* `MERCURE_PUBLIC_HUB_URL`: 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`: 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 but `MERCURE_PUBLIC_HUB_URL` was, the former one will be used to publish updates.
-* `MERCURE_JWT_SECRET`: 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.
-* `ANONYMIZE_REMOTE_ADDR`: Tells if IP addresses from visitors should be obfuscated before storing them in the database. Default value is `true`. **Careful!** Setting this to `false` will make your Shlink instance no longer be in compliance with the GDPR and other similar data protection regulations. 
-* `REDIRECT_STATUS_CODE`: Either **301** or **302**. Used to determine if redirects from short to long URLs should be done with a 301 or 302 status. Defaults to 302.
-* `REDIRECT_CACHE_LIFETIME`: Allows to set the amount of seconds that redirects should be cached when redirect status is 301. Default values is 30. 
-
-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 \

-## Provide config via volumes
+## Full documentation
 
-Rather than providing custom configuration via env vars, it is also possible ot provide config files in json format.
+All the features supported by Shlink are also supported by the docker image.
 
-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",

-```
-
-> 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-architecture
-
-Starting on v2.3.0, Shlink's docker image is built for multiple architectures.
-
-The only limitation is that images for architectures other than `amd64` will not have support for Microsoft SQL databases, since there are no official binaries.
-
-## 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, 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.

+# Support restrictions and permissions in API keys
+
+* Status: Accepted
+* Date: 2021-01-17
+
+## Context and problem statement
+
+Historically, every API key generated for Shlink granted you access to all existing resources.
+
+The intention is to be able to apply some form of restriction to API keys, so that only a subset of "resources" can be accessed with it, naming:
+
+* Allowing interactions only with short URLs and related resources, that have been created with the same API key.
+* Allowing interactions only with short URLs and related resources, that have been attached to a specific domain.
+
+The intention is to implement a system that allows adding to API keys as many of these restrictions as wanted.
+
+Supporting more restrictions in the future is also desirable.
+
+## Considered option
+
+* Using an ACL/RBAC library, and checking roles in a middleware.
+* Using a service that, provided an API key, tells if certain resource is reachable while it also allows building queries dynamically.
+* Using some library implementing the specification pattern, to dynamically build queries transparently for outer layers.
+
+## Decision outcome
+
+The main difficulty on implementing this is that the entity conditioning the behavior (the API key) comes in the request in some form, but it can potentially affect database queries performed in the persistence layer.
+
+Because of this, it has to traverse all the application layers from top to bottom, in most of the cases.
+
+This motivated selecting the third option, as we can propagate the API key and delay its handling to the last step, without changing the behavior of the rest of the layers that much (except in some individual use cases).
+
+The domain term used to refer these "restrictions" is finally **roles**.
+
+It can be combined in the future with an ACL/RBAC library, if we want to restrict access to certain resources, but it didn't fulfil the initial requirements.
+
+## Pros and Cons of the Options
+
+### An ACL/RBAC library
+
+* Good, because there are many good libraries out there.
+* Bad, because when you need to filter resources lists this kind of libraries doesn't really work.
+
+### A service with the logic
+
+* Bad, because it would need to be used in many layers of the application, mixing unrelated concerns.
+
+### A library implementing the specification pattern
+
+* Good, because allows centralizing the generation of dynamic specs by the entity itself, that are later translated automatically into database queries.

+# Track visits to 'base_url', 'invalid_short_url' and 'regular_404'
+
+* Status: Accepted
+* Date: 2021-02-07
+
+## Context and problem statement
+
+Shlink has the mechanism to return either custom errors or custom redirects when visiting the instance's base URL, an invalid short URL, or any other kind of URL that would result in a "Not found" error.
+
+However, it does not track visits to any of those, just to valid short URLs.
+
+The intention is to change that, and allow users to track the cases mentioned above.
+
+## Considered option
+
+* Create a new table to track visits o this kind.
+* Reuse the existing `visits` table, by making `short_url_id` nullable and adding a couple of other fields.
+
+## Decision outcome
+
+The decision is to use the existing table, as making the short URL nullable can be handled seamlessly by using named constructors, and it has a lot of benefits on regards of reusing existing components.
+
+Also, the domain name this kind of visits will receive is "Orphan Visits", as they are detached from any existing short URL.
+
+## Pros and Cons of the Options
+
+### New table
+
+* Good because we don't touch existing models and tables, reducing the risk to introduce a backwards compatibility break.
+* Bad because we will have to repeat data modeling and logic, or refactor some components to support both contexts. This in turn increases the options to introduce a BC break.
+
+### Reuse existing table
+
+* Good because all the mechanisms in place to handle visits will work out of the box, including locating visits and such.
+* Bad because we will have more optional properties, which means more double checks in many places.

+# Migrate to a new caching library
+
+* Status: Accepted
+* Date: 2021-08-05
+
+## Context and problem statement
+
+Shlink has always used the `doctrine/cache` library to handle anything related with cache.
+
+It was convenient, as it provided several adapters, and it was the library used by other doctrine packages.
+
+However, after the creation of the caching PSRs ([PSR-6 - Cache](https://www.php-fig.org/psr/psr-6) and [PSR-16 - Simple cache](https://www.php-fig.org/psr/psr-16)), most library authors have moved to those interfaces, and the doctrine team has decided to recommend using any other existing package and decommission their own solution.
+
+Also, Shlink needs support for Redis clusters and Redis sentinels, which is not supported by `doctrine/cache` Redis adapters.
+
+## Considered option
+
+After some research, the only packages that seem to support the capabilities required by Shlink and also seem healthy, are these:
+
+* [Symfony cache](https://symfony.com/doc/current/components/cache.html)
+    * 🟢 PSR-6 compliant: **yes**
+    * 🟢 PSR-16 compliant: **yes**
+    * 🟢 APCu support: **yes**
+    * 🟢 Redis support: **yes**
+    * 🟢 Redis cluster support: **yes**
+    * 🟢 Redis sentinel support: **yes**
+    * 🟢 Can use redis through Predis: **yes**
+    * 🔴 Individual packages per adapter: **no**
+* [Laminas cache](https://docs.laminas.dev/laminas-cache/)
+    * 🟢 PSR-6 compliant: **yes**
+    * 🟢 PSR-16 compliant: **yes**
+    * 🟢 APCu support: **yes**
+    * 🟢 Redis support: **yes**
+    * 🟢 Redis cluster support: **yes**
+    * 🔴 Redis sentinel support: **no**
+    * 🔴 Can use redis through Predis: **no**
+    * 🟢 Individual packages per adapter: **yes**
+
+## Decision outcome
+
+Even though Symfony packs all their adapters in a single component, which means we will install some code that will never be used, Laminas relies on the native redis extension for anything related with redis.
+
+That would make Shlink more complex to install, so it seems Symfony's package is the option where it's easier to migrate to.
+
+Also, it's important that the cache component can share the Redis integration (through `Predis`, in this case), as it's also used by other components (the lock component, to name one).
+
+## Pros and Cons of the Options
+
+### Symfony cache
+
+* Good because it supports Redis Sentinel.
+* Good because it allows using a external `Predis` instance.
+* Bad because it packs all the adapters in a single component.
+
+### Laminas cache
+
+* Good because allows installing only the adapters you are going to use, through separated packages.
+* Bad because it requires the php-redis native extension in order to interact with Redis.
+* Bad because it does ot seem to support Redis Sentinels.
