 ### Default rooms
-There is a shorthand syntax specialized for convenience for these values. The server name is optional for local room IDs.
-The same rule applies to local aliases in addition to not requiring the pound sign prefix.
 
 #### Example
+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.
 In this example, the two configuration options are equivalent:
 ```toml
-default_rooms = ["#home",            "lounge",             "!abc123",            "#conduit:fachschaften.org"]
-default_rooms = ["#home:conduit.rs", "#lounge:conduit.rs", "!abc123:conduit.rs", "#conduit:fachschaften.org"]
+default_rooms = ["#home",            "!abc123",            "#conduit:fachschaften.org"]
+default_rooms = ["#home:conduit.rs", "!abc123:conduit.rs", "#conduit:fachschaften.org"]
 ```
