+###XMPP Features
+SC works with every XMPP server out there. However XMPP is an extensible
+protocol. These extensions are standardized as well in so called XEP’s. SC
+supports a couple of those to make the overall userexperience better. There is a
+chance that your current XMPP server does not support these extensions.
+Therefore to get the most out of SC you should consider either switching to an
+XMPP server that does or - even better - run your own XMPP server for you and
+your friends.
+These XEPs are - as of now:
+* XEP-0280: Message Carbons which automatically syncs the messages you send to
+  your desktop client and thus allows you to switch seamlessly from your mobile
+  client to your desktop client and back within one conversation.
+* XEP-0237: Roster Versioning mainly to save bandwith on poor mobile connections
