-## Docker
 
-Start a container using the official Docker image.
-```
-docker run --name maputnik -p 8888:8888 -d maputnik/editor
-```
+## Tests
+For testing we use [webdriverio](http://webdriver.io) and [selenium-standalone](https://github.com/vvo/selenium-standalone)
 
-Stop the container
+[selenium-standalone](https://github.com/vvo/selenium-standalone) starts a server that will launch browsers on your local machine. We use chrome so you **must** have chrome installed on your machine.
+
+Now open and terminal and run the following. This will install the drivers on your local machine
 
 ```
-docker stop maputnik
+./node_modules/.bin/selenium-standalone install
 ```
 
+Now start the standalone server
+
+```
+./node_modules/.bin/selenium-standalone start
+```
+
+Then open another terminal and run
+
+```
+npm test
+```
+
+After some time you should see a browser launch which will be automated by the test runner.
