+docker-compose -d up rovers-postgres rovers-rabbitmq
 ```

+Export as environment variables the API keys([see section](#supported-providers)).Then, you can execute rovers:
 ```bash
-docker run -d --hostname rabbitmq --name rabbitmq -p 8081:15672 -p 5672:5672 rabbitmq:3-management
+docker-compose up --no-deps rovers
 ```
 
-Then, you can execute rovers using docker:
+If you need run just some of the availables supported-providers, you can use this command replacing the flag `--provider` with those providers you want to use:
 ```bash
-docker run --name rovers --link rabbitmq --link postgres \
-  -e CONFIG_GITHUB_TOKEN=[REPLACEWITHGHKEY] \
-  -e CONFIG_BING_KEY=[REPLACEWITHBINGKEY] \
-  srcd/rovers /bin/sh -c "rovers initdb; rovers repos --queue=rovers"
+docker-compose run --rm --no-deps --service-ports rovers /bin/sh -c "rovers initdb; rovers repos --provider=github --provider=bitbucket"
 ```
+
 After that, rovers will generate a lot of 'mentions' (git repositories found on the internet), and sending them to the 'rovers' queue in Rabbit.
 
+To stop and remove all the containers running `docker-compose down`
+
 Finally, you can use [Borges](https://github.com/src-d/borges) to fetch the content of these repositories.
