 XMPP gateway for the IRC network
 
 **Shipped version:** 8.3~ynh2
-## Disclaimers / important information
-
-Once biboumi_ynh is installed you can use any XMPP client software to join IRC channels. Any IRC channel is seen as a standard XMPP chatroom (aka MUC) with a special name.  
-The the name is formatted like this: `#channelname%ircservername@biboumi.yourdomain.tld`.
-
-For example, if you have a YunoHost server hosting domain *example.net* and you want to join the channel *#yunohost* on *irc.freenode.net* you simply need to join the MUC `#yunohost%irc.freenode.net@biboumi.example.net`.
-
-* Any known limitations, constrains or stuff not working, such as (but not limited to):
-    * Currently, Biboumi is only tested with one domain and it must be the main domain of your YunoHost server.
-
-* Other infos that people should be aware of, such as:
-    * You can configure Biboumi with the file `/etc/biboumi/biboumi.cfg`.
