+client.
+
+Most of the features you would expect from a chat application are missing right
+now but we are getting close to a more feature complete client.  Specifically
+there is support for:
+@itemize
+@item E2E encryption (text messages only: attachments are currently sent unencrypted).
+@item User registration.
+@item Creating, joining & leaving rooms.
+@item Sending & receiving invites.
+@item Sending & receiving files and emoji.
+@item Typing notifications.
+@item Username auto-completion.
+@item Message & mention notifications.
+@item Redacting messages.
+@item Read receipts.
+@item Basic communities support.
+@item Room switcher (@key{ctrl-K}).
+@item Light, Dark & System themes.
