 If you don't feel like setting up databases and users, you can use our [docker](http://docker.io) [image](https://index.docker.io/u/mhansen/sequelize-contribution/) for sequelize contribution.
 
 Getting the image:
-
-```sudo docker pull mhansen/sequelize-contribution```
+```console
+sudo docker pull mhansen/sequelize-contribution
+```
 
 Start the container and save references to container id and ip:
 
-```CONTAINER=$(sudo docker run -d -i -t mhansen/sequelize-contribution)
-CONTAINER_IP=$(sudo docker inspect -format='{{.NetworkSettings.IPAddress}}' $CONTAINER)```
+```console
+CONTAINER=$(sudo docker run -d -i -t mhansen/sequelize-contribution)
+CONTAINER_IP=$(sudo docker inspect -format='{{.NetworkSettings.IPAddress}}' $CONTAINER)
+```
 
 Run tests:
 
-```SEQ_HOST=$CONTAINER_IP SEQ_USER=sequelize_test make all```
+```console
+SEQ_HOST=$CONTAINER_IP SEQ_USER=sequelize_test make all
+```
 
 Stop the container:
 
-```sudo docker stop $container```
+```console
+sudo docker stop $container
+```
 
 When running tests repeatedly, you only need to redo step 3 if you haven't stopped the container.
