+# Contributing
+This is for people who want to contribute to the project.
+
+## How to get started
+
+First of all, you need to fork the repository and clone it locally.
+After that, we've prepared a docker setup to help you get started quickly.
+
+Install docker and docker-compose on your machine, then run the following commands:
+
+```bash
+docker-compose up -d
+docker-compose exec php-fpm bash
+```
+
+When you are on the container, you can install the dependencies with composer:
+
+```bash
+composer install
+```
+
+Now you can execute the tests with the following command:
+
+```bash
+./vendor/bin/phpunit
+```
