 You should look at and run the tests to see what happens in the example.
 To do this, you should install dependencies with `Composer` first:
 
-### [optional] Using Docker
-
-You can optionally run tests using [Docker for Mac](https://www.docker.com/docker-mac) or [Windows](https://www.docker.com/docker-windows) or native one for [Linux](https://www.docker.com/docker-debian).
-Just run:
-```
-docker-compose up
-```
-
-### Install dependencies
-
 ```bash
 $ composer install
 ```
 
 Read more about how to install and use `Composer` on your local machine [here](https://getcomposer.org/doc/00-intro.md#installation-linux-unix-osx).
 
-If you are using Docker, you just have to run:
-
-```bash
-docker-compose run composer install
-```
-
-### Running test suite
+To run the tests use `phpunit`:
 
 ```bash
 $ ./vendor/bin/phpunit
 ```

 ## Patterns
 
 The patterns can be structured in roughly three different categories. Please click on the [:notebook:](http://en.wikipedia.org/wiki/Software_design_pattern) for a full explanation of the pattern on Wikipedia.
