 ## Development
 Since the engelsystem is open source, you can help to improve the system. We really love to get pull requests containing fixes or implementations of our Github issues.
 
 Please create single pull requests for every feature instead of creating one big monster of pull request containing a complete rewrite.
 
+### Testing
+To run the unit tests use
+```bash
+vendor/bin/phpunit --testsuite Unit
+``` 
+
+If a database is configured and the engelsystem is allowed to mess around with some files, you can run feature tests. The tests can potentially delete some database entries, so they should never be run on a production system!
+```bash
+vendor/bin/phpunit --testsuite Feature
+# or for unit- and feature tests:
+vendor/bin/phpunit
+``` 
+
+### CI & Build Pipeline
+The engelsystem can be tested and automatically deployed to a testing/staging/production environment.
+This functionality requires a [GitLab](https://about.gitlab.com/) server with a running docker minion.
+
+To use the deployment features the following secret variables need to be defined (if undefined the step will be skipped):
+```bash
+SSH_PRIVATE_KEY         # The ssh private key
+STAGING_REMOTE          # The staging server, e.g. user@remote.host
+STAGING_REMOTE_PATH     # The psth on the remote server, e.g. /var/www/engelsystem
+PRODUCTION_REMOTE       # Same as STAGING_REMOTE but for the production environment
+PRODUCTION_REMOTE_PATH  # Same as STAGING_REMOTE_PATH but for the production environment
+```
+
+#### deploy.sh
+The `deploy.sh` script can be used to deploy the engelsystem. It uses rsync to deploy the application to a server over ssh.
+
+For usage see `./deploy.sh -h`
+
 ### Codestyle
 Please ensure that your pull requests follow [PSR-2](http://www.php-fig.org/psr/psr-2/) and [PSR-4](http://www.php-fig.org/psr/psr-4/).
