+### Caveats
+
+Litharge uses [AutoRegister](https://github.com/ncoevoet/AutoRegister) to
+create accounts on the bot based on network services accounts.  Currently, the
+controls for directly managing channel/capability associtations are restricted
+and can only be accessed by network staff.
+
+This means, when you remove flags for a user you must also request staff
+assistance to remove the corrisponding settings from litharge (given that user
+was oberved by litherage setting a ban or quiet in the given channel).
+
+See the [FAQ](https://libera.chat/guides/faq#how-to-find-libera-chat-staff)
+for information on how to contact staff.
