+### Being added as a maintainer to an existing implementation
+
+At any point, a world maintainer can approve the addition of another maintainer to their world.  
+In order to do this, either an existing maintainer or the new maintainer must open a PR updating the
+[CODEOWNERS](/docs/CODEOWNERS) file.  
+This change must be approved by all existing maintainers of the affected world, the new maintainer candidate, and
+one core maintainer.  
+To help the core team review the change, information about the new maintainer and their contributions should be
+included in the PR description.
