+name: 💌 Add a new committer and PMC member

+about: Steps that need to be done in order to add a new committer and PMC member

+

+---

+

 **DO NOT** add the potential candidate's name here since a vote can fail, an invitation can be rejected, or the Apache Board can veto PMC inclusion (but not the vote for a committer).

 

 See the [README](../README.md) for details on each of the steps.
