+# 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.

-## Supported env vars
+## 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.
 
@@ -113,24 +168,25 @@ This is the complete list of supported env vars:
 * `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.
-* `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.
-
 * `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. 
+* `PORT`: Can be used to set the port in which shlink listens. Defaults to 8080 (Some cloud providers, like Google cloud or Heroku, expect to be able to customize exposed port by providing this env var).
