 Merge requests can be filed either at [gitlab.com](https://gitlab.com/gitlab-org/gitlab-ce/merge_requests) or [github.com](https://github.com/gitlabhq/gitlabhq/pulls).
 
+If you are new to GitLab development (or web development in general), search for the label `easyfix` ([gitlab.com](https://gitlab.com/gitlab-org/gitlab-ce/issues?label_name=easyfix), [github](https://github.com/gitlabhq/gitlabhq/labels/easyfix)). Those are issues easy to fix, marked by the GitLab core-team. If you are unsure how to proceed but want to help, mention one of the core-team members to give you a hint.

 ### Merge request guidelines
 
 If you can, please submit a merge request with the fix or improvements including tests. If you don't know how to fix the issue but can write a test that exposes the issue we will accept that as well. In general bug fixes that include a regression test are merged quickly while new features without proper tests are least likely to receive timely feedback. The workflow to make a merge request is as follows:
