   # ### CI Setup
-  #
   # Ah Jenkins, so many memories. So, if you're using Jenkins, you're hosting your own environment. You
-  # will want to be using the [GitHub pull request builder plugin](https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin)
+  #
+  # #### GitHub
+  # You will want to be using the [GitHub pull request builder plugin](https://wiki.jenkins-ci.org/display/JENKINS/GitHub+pull+request+builder+plugin)
   # in order to ensure that you have the build environment set up for PR integration.
   #
   # With that set up, you can edit your job to add `bundle exec danger` at the build action.
   #
+  # ### GitLab
+  #
+  # You will want to be using the [GitLabe Plugin](https://github.com/jenkinsci/gitlab-plugin)
+  # in order to ensure that you have the build environment set up for PR integration.
+  #
+  # With that set up, you can edit your job to add `bundle exec danger` at the build action.
+  #
   # ### Token Setup
   #
   # As you own the machine, it's up to you to add the enviroment variable for the `DANGER_GITHUB_API_TOKEN`.
