+# World Maintainer
+
+A world maintainer is a person responsible for a world or part of a world in Archipelago.
+
+If a world author does not want to take on the responsibilities of a world maintainer, they can release their world as
+an unofficial [APWorld](/docs/apworld%20specification.md) or maintain their own fork instead.
+
+
+## Responsibilities
+
+Unless these are shared between multiple people, we expect the following from each world maintainer
+
+* Be on our Discord to get updates on problems with and suggestions for the world.
+* Decide if a feature (pull request) should be merged.
+* Review contents of such pull requests or organize peer reviews or post that you did not review the content.
+* Fix or point out issues when core changes break your code.
+* Use the watch function on GitHub, the #github-updates channel on Discord or check manually from time to time for new
+  pull requests. Core maintainers may also ping you if a pull request concerns your world.
+* Test (or have tested) the world on the main branch from time to time, especially during RC (release candidate) phases
+  of development.
+* Let us know of long unavailabilities.
+
+
+## Becoming a World Maintainer
+
+### Adding a World
+
+When we merge your world into the core Archipelago repository, you automatically become world maintainer unless you
+nominate someone else (i.e. there are multiple devs).
+
+### Getting Voted
+
+When a world is unmaintained, the [core maintainers](https://github.com/orgs/ArchipelagoMW/people)
+can vote for a new maintainer if there is a candidate.
+For a vote to pass, the majority of participating core maintainers must vote in the affirmative.
+The time limit is 1 week, but can end early if the majority is reached earlier.
+Voting shall be conducted on Discord in #archipelago-dev.
+
+
+## Dropping out
+
+### Resigning
+
+A world maintainer can resign. If no new maintainer steps up and gets voted, the world becomes unmaintained.
+
+### Getting Voted out
+
+A world maintainer can be voted out by the [core maintainers](https://github.com/orgs/ArchipelagoMW/people),
+for example when they become unreachable.
+For a vote to pass, the majority of participating core maintainers must vote in the affirmative.
+The time limit is 2 weeks, but can end early if the majority is reached earlier AND the world maintainer was pinged and
+made their case or was pinged and has been unreachable for more than 2 weeks already.
+Voting shall be conducted on Discord in #archipelago-dev. Commits that are a direct result of the voting shall include
+date, voting members and final result in the commit message.
+
+
+## Handling of Unmaintained Worlds
+
+As long as worlds are known to work for the most part, they can stay included. Once a world becomes broken it shall be
+moved from `worlds/` to `worlds_disabled/`.
