+### Being added as a maintainer to an existing implementation
+
+At any point, a world maintainer can approve the addition of another world maintainer to their world.

+One of the involved parties can open a pull request with a change to this document. This PR must then be approved by all of the other involved parties.
+
+This should usually be a quick process, but core reserves its right to make their own assessment.  
+For example, adding 5 people who we have never heard of might raise some questions.
