+This project bridges between matrix and telegram.
+
+Telegram users can now participate in matrix rooms, while choosing
+which room to "focus" (send and receive messages) at a time.
+Our goal is to provide full matrix user experience, including support of
+all media types, relaying "typing..." messages, etc..
