    made each week, e.g. updating an article to be in sync with the English
    version, removing or fixing a bad quality article…
 
 If no progress is made on a locale in these areas within 1 month, the locale
 will be considered inactive, and edits will stop being accepted.

+### Promoting an inactive locale to Tier 1
+
+If you want to promote a currently-inactive/frozen locale to Tier 1, meaning
+that it is activated and can then be edited, you need to put together a
+community maintenance team. This requires:
+
+- A team lead who will be the communication point between that team and the MDN
+  core team, and have overall responsibility for the team.
+- At least one other member, so that one member can review another member's
+  work.
+- A place to discuss this team's localization work. This can be a Telegram
+  group, Matrix chat room, or whatever the team thinks is best.
