+Single and app and data images
+===================
 
-How to build and use images yourself
+Normally docker uses a single image for one applications.
+But GitLab stores repositories and uploads in the filesystem.
+This means that upgrades of a single image are hard.
+That is why we recommend using separate app and data images.
+We'll first describe how to use a single image.
+After that we'll describe how to use the app and data images.
+
+Single image
+=================
+
+Run the below commands from the GitLab repo root directory.
+People using boot2docker should run the commands without sudo.
+
+Build the image with:
+
+```
+sudo docker build --tag gitlab-ce docker/single/
+```
+
+Run the image with:
+
+```
+sudo docker run --detach --name gitlab-ce --publish 8080:80 --publish 2222:22 gitlab-ce
+```
+
+You can then go to [http://localhost:8080/](http://localhost:8080/) or [http://192.168.59.103:8080/](http://192.168.59.103:8080/) if you use boot2docker.
+
+You can login with username `root` and password `5iveL!fe`.
+Next time, you can just use `sudo docker start gitlab-ce` and `sudo docker stop gitlab-ce`.
+
+Publish the image with:
+
+```bash
+sudo docker commit -m "Initial commit" -a "Sytse Sijbrandij" gitlab-ce sytse/gitlab-ce:7.10.1
+sudo docker push sytse/gitlab-ce:7.10.1
+```
+
+Use the published image with:
+
+```bash
+sudo docker pull sytse/gitlab-ce:7.10.1
+sudo docker run --detach --name gitlab-ce --publish 8080:80 --publish 2222:22 sytse/gitlab-ce:7.10.1
+```
+
+Troubleshoot with:
+
+```
+sudo docker run -ti -e TERM=linux --name gitlab-ce --publish 8080:80 --publish 2222:22 sytse/gitlab-ce:7.10.1 bash
+/opt/gitlab/embedded/bin/runsvdir-start & gitlab-ctl reconfigure
+gitlab-ctl start
+```
