+## Docker
+
+We provide a docker-compose that you can use out of the box:
+
+``` 
+$ docker-compose build
+$ HOST=mydomain.com PORT=3001 docker-compose up -d
+```
+
+You can now find your gekko instance running on mydomain.com:3001. 
+By default these are set to:
+
+```
+HOST=localhost
+PORT=3000
+``` 
+
