@ -45,8 +45,9 @@ One of the following options **must** be supplied:
information. These are the same values seen as `base_url` in the `default_server_config` example, with `default_is_url`
being optional.
If a combination of these three methods is used then Element will fail to load. This is because it is unclear which
should be considered "first".
If both `default_server_config` and `default_server_name` are used, Element will try to look up the connection
infomation using `.well-known`, and if that fails, take `default_server_config` as the homeserver connection
infomation.
