+## Using Housekeeper in other projects
+
+Right now we do not publish housekeeper to RubyGems. We have published it once
+to hold the name but it's not up to date.
+
+In order to use Housekeeper in another project you would need to add the
+following to your `Gemfile` and run `bundle install`:
+
+```
+gem 'gitlab-housekeeper', git: 'https://gitlab.com/gitlab-org/gitlab.git', branch: 'master', glob: 'gems/gitlab-housekeeper/*.gemspec'
+```
+
+After that you can just run `bundle exec gitlab-housekeeper`. Housekeeper
+defaults to loading all keeps in the `./keeps` directory so you would also
+create that directory in your project and put your keeps there.
