 ### Default rooms
-Since the validation of room aliases and IDs does validate the presence of a colon separator,
-this symbol including the server name can be ommitted for local rooms.
+This list should contain either room identifiers or aliases.
+Opaque identifiers will be interpreted as incomplete, local aliases.
 
 #### Example
-In this example, the two configuration options are equivalent:
+In this example, the opaque identifier and alias are the same:
 ```toml
-default_rooms = ["#home",            "!abc123",            "#conduit:fachschaften.org"]
-default_rooms = ["#home:conduit.rs", "!abc123:conduit.rs", "#conduit:fachschaften.org"]
+default_rooms = ["home", "#home:conduit.rs"]
 ```
