+summary: 'Require MUC occupant nicknames to match a specific pattern'
+---
+
+Introduction
+============
+
+This checks the nickname of a joining user against a configurable
+[Lua pattern](https://www.lua.org/manual/5.2/manual.html#6.4.1), and prevents
+them from joining if it does not match.
+
+Configuration
+=============
+
+There is a single configuration option, `muc_restrict_nick_pattern` and the
+default is `"^%w+$"` - i.e. allow only alphanumeric characters in nicknames.
+
+Compatibility
+=============
+
+Requires Prosody 0.11 or higher.
