+Requirements:
+We try to keep requirements to a minimum, but we suggest that you install http://dnspython.org although it isn't strictly required.
+If you do not install this library, you main need to specify server/port for services that use SRV records (like GTalk).
+"sudo pip install dnspython" on a *nix system with pip installed.

 SleekXMPP has several design goals/philosophies:

 - Every XEP as a plugin.
