+What is GitLab?
+===============
+
+GitLab offers git repository management, code reviews, issue tracking, activity feeds, wikis. It has LDAP/AD integration, handles 25,000 users on a single server but can also run on a highly available active/active cluster. A subscription gives you access to our support team and to GitLab Enterprise Edition that contains extra features aimed at larger organizations.

+
+
+How to use this image.
+======================
+
+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
+
+This empty container will exist to persist as volumes the 3 directories used by GitLab, so remember not to delete it:
+
+- `/var/opt/gitlab` for application data
+- `/var/log/gitlab` for logs
+- `/etc/gitlab` for configuration
+
+Then run GitLab:
+
+	docker run --detach --name gitlab --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data genezys/gitlab:7.5.1
+
+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`.
+
+
+How to configure GitLab.
+========================
+
+This container uses the official Omnibus GitLab distribution, so all configuration is done in the unique configuration file `/etc/gitlab/gitlab.rb`.
+
+To access GitLab configuration, you can start a new container using the shared data volume container:
+
+	docker run -ti --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.
+
+You can find all available options in [GitLab documentation](https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md#configuration).
