I would like to start contributing to Gitlab CE. This will be my first time contributing to an open-source projet. I read https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CONTRIBUTING.md and feel ready to try on issues from https://gitlab.com/gitlab-org/gitlab-ce/issues?scope=all&state=opened&utf8=✓&label_name=up-for-grabs
Is there a guideline to chose an issue from this list ? Are they prioritized in some way ?
How should I indicate my choice ? Assign the issue to myself ?
Thank you for your help.
