+A compose.yml is included for deployment as well. To run the Docker compose 
+with MariaDB, redis and ethgas station API. **(you need to have ethgasstation_backend running and eth-node)**:
+
+```
+docker-compose -f compose.yml build
+docker-compose -f compose.yml up
+```
+
 This will expose and forward port 8080 from the image. Note that the docker
 image runs in production mode by default.
