+summary: "Automatically register new MUC participants as members"
+...
+
+# Introduction
+
+This module automatically makes anybody who joins a MUC become a registered
+member. This can be useful for certain use cases.
+
+Note: there is no automatic cleanup of members. If you enable this on a server
+with busy public channels, your member list will perpetually increase in size.
+
+Also, there is currently no per-room option for this behaviour. That may be
+added in the future, along with membership expiry.
+
+# Configuration
+
+There is currently no configuration for this module. The module should be
+enabled on your MUC component, i.e. in the modules_enabled option under your
+Component:
+
+``` {.lua}
+Component "conference.example.com" "muc"
+    modules_enabled = {
+        "muc_auto_member";
+    }
+```
+
+# Compatibility
+
+0.12 and later.
