   sudo systemctl stop gitlab
   sudo systemctl stop gitlab-workhorse
   sudo systemctl stop gitlab-sidekiq
   sudo systemctl stop gitaly
   sudo -u postgres psql -e 'DROP DATABASE gitlab; DROP ROLE gitlab;'
   sudo systemctl start gitlab
   sudo systemctl start gitlab-workhorse
   sudo systemctl start gitlab-sidekiq
   sudo systemctl start gitaly

2. Create a `ghc` group.
3. Create a `ghc` project in said group.
4. Copy `Settings.hs.dist` into `Settings.hs`
4. Set `project` in `Settings.hs` to the project ID of the `ghc` project
5. Add an access token for root, update `gitlabToken` in `Settings.hs`.
6. Set `gitlabBaseUrl` in `Settings.hs`
7. Adjust other settings in `Settings.hs` as needed
8. Build & run it
