+### 1. Update passwd/group file
+
+Update the `/etc/group` file, and change the gid of the group
+
+```bash
+git:x:500:
+```
+or you can run the following command
+
+```bash
+groupmod -g 500 git
+```
+
+Amended the `/etc/passwd` file to change the uid, gid and the home directory for git
+
+```bash
+git:x:500:500:GitLab,,,:/var/lib/git:/bin/bash
+```
+or you can run the following command
+
+```bash
+usermod -d /var/lib/git -g 500 -u 500 git
+```
+
+### 2. Move the git folder
+
+```bash
+cp -r /home/git /var/lib/

+chown -R git:git /var/lib/git
+```
+
+### 4. Update Gitlab config files
+update `~git/gitlab/config/gitlab.yml`, using the following command
+
+```bash
+sed -i -e 's/\/home/\/var\/lib/g' ~git/gitlab/config/gitlab.yml

+### 6. Update authorized_keys

+sed -i -e 's/\/home/\/var\/lib/g' ~git/.ssh/authorized_keys
+```
+

+
+update `/etc/nginx/sites-enabled/gitlab`, using the following command
+
+```bash
+sed -i -e 's/\/home/\/var\/lib/g' /etc/nginx/sites-enabled/gitlab
+```
+
+### 8. Add/Update gitlab service and default files
+
+We need to apply the following patch to `/etc/init.d/gitlab`, This has been submitted as a 
+PR already to gitlabhq. This enables to read the default file, and initialises other variables.
+Without this diff, other variables then also need to be defined in `/etc/default/gitlab`

+```
+
+If you haven't already, copy the service default file, then do so, and then update the file to point to the new home directory
+
+```bash
+cp ~git/gitlab/lib/support/init.d/gitlab.default.example /etc/default/gitlab
+sed -i -e 's/\/home/\/var\/lib/g' /etc/default/gitlab
+```
+
+### 9. Update gitlab-shell hooks
+
+The file `~git/gitlab-shell/support/rewrite-hooks.sh`, has the home directory hardcoded, so we need to update this file as well
+
+```bash
+sed -i -e 's/\/home/\/var\/lib/g' ~git/gitlab-shell/support/rewrite-hooks.sh
+```
+
+Now we update all the hooks
+
+```bash
+cd ~git
+sudo -u git -H gitlab-shell/support/rewrite-hooks.sh
+```
+
+### 10. Restart application
+
+```bash
+sudo service gitlab restart
+sudo service nginx restart
+```
+
+### 11. Check application status
+
+Check if GitLab and its environment are configured correctly:
+
+    cd ~git/gitlab
+    sudo -u git -H bundle exec rake gitlab:env:info RAILS_ENV=production
+
+To make sure you didn't miss anything run a more thorough check with:
+
+    cd ~git/gitlab
+    sudo -u git -H bundle exec rake gitlab:check RAILS_ENV=production
+
+### 12. Remove old home
+
+Once you are happy that everything is now working in the new directory, you can remove the old `/home/git`
+
+    rm -rf /home/git
