+### How to add a new project to GitLab CI
+
+1) Log in the GitLab CI web interface
+2) Press the 'Sync now' button
+3) Select your project with the 'Add' button
+4) Go the the Integration page and do the 'Complete (as service)' steps
+5) Go to the settings page to add a build script (see below for an example)
+6) Push a new commit to the project
+7) If the build fails then adjust the build script and press the 'Retry' button on the build page
+8) If the build is green you are done, all new commits will be tested and you see the status of merge requests builds within GitLab
+
+For your information, the runner runs the line below and then runs the commands in your build script:
+
+    cd /gitlab-ci-runner/tmp/builds && git clone git@gitlab_server_fqdn:group/project.git project-1 && cd project-1 && git checkout master
+
+Build script example:
+
+    bundle install
+    bundle exec rake db:create RAILS_ENV=test
+    bundle exec rake db:migrate RAILS_ENV=test
+    script/run_all_tests
