 * `hosts.bare`: Just the (sub)domain of the server.
 * `user_id_format`: A Python `str.format`-style string to format user IDs as
 * `db_url`: A SQLAlchemy URL for the database. See the [SQLAlchemy docs](http://docs.sqlalchemy.org/en/latest/core/engines.html).
+* `bot_owners`: A list of matrix users the bot won't use a `<username>` prefix for. Can be left blank to print a prefix for all matrix users. Useful if you would like the bridge to replace Telegram for yourself, but also want to allow others to use the Matrix room.
+* `print_url_with_image`: Set to `false` to disable sending the Matrix url of an image to Telegram.
