+# Advanced
+
+Advanced settings options are provided for the sake of allowing admins to tune their instance to their liking.
+
+These are set to sensible defaults, so most server admins won't need to touch them or think about them.
+
+**Changing these settings if you don't know what you're doing may break your instance**.
