 ### Committer status
 Similar to [Chromium's committer status](https://dev.chromium.org/getting-involved/become-a-committer), long-term contributors to the ANGLE project may request to join the `angle-committers` group.  This allows you to give `+2` on code reviews and land patches without assistance.  After about 6 months of regular contributions, you may request committer status from a core ANGLE team member via email or code review.  Chromium committers may ask at any time.
