 I recommend creating a data volume container first, this will simplify migrations and backups:
 
-	docker run --name gitlab_data genezys/gitlab:7.5.1 /bin/true
+```bash
+docker run --name gitlab_data genezys/gitlab:7.5.1 /bin/true

 This empty container will exist to persist as volumes the 3 directories used by GitLab, so remember not to delete it:

-You can then go to `http://localhost:8080/` (or most likely `http://192.168.59.103:8080/` if you use boot2docker). Next time, you can just use `docker start gitlab` and `docker stop gitlab`.
+The first run will take a while as GitLab needs to configure itself.

 This container uses the official Omnibus GitLab distribution, so all configuration is done in the unique configuration file `/etc/gitlab/gitlab.rb`.

+```bash
+docker run -ti -e TERM=linux --rm --volumes-from gitlab_data ubuntu 
+vi /etc/gitlab/gitlab.rb

 **Note** that GitLab will reconfigure itself **at each container start.** You will need to restart the container to reconfigure your GitLab.
