+The purpose of this project is **not** to provide an alternative to the original
+Discord client. Rather, it should be used in addition to the original client in
+case you want to stream something, maybe used with a second account. For
+anything else, this client has way too many things that work less well than in
+the original client.

 ## Known Issues
 
 - Only works with **PipeWire**
 - Only works on **X11**
-- Can only share primary screen (no other screens or specific applications) (see [#1](https://github.com/maltejur/discord-screenaudio/issues/1))
