+a) apt-get install libqxmpp-dev psi ejabberd
+
+b) edit /etc/ejabberd/ejabberd.cfg to allow inband registration:
+
+   --8<---
+   %% No username can be registered via in-band registration:
+   %% To enable in-band registration, replace 'deny' with 'allow'
+   % (note that if you remove mod_register from modules list then users will not
+   % be able to change their password as well as register).
+   % This setting is default because it's more safe.
+   {access, register, [{allow, all}]}.
+   --8<---
+
+c) start psi and configure it to use 'localhost' as server and create two
+    accounts: <yourname>:<yourpass>
+              qtapp:test
+
+d) login with <yourname> and qtapp, add both accounts to their contact list,
+    and try to send messages. logoff the qtapp account.
+
+e) build the qt client application and start it:
+
+qmake
+make
+./client
+
+f) the qtapp account needs now to be online in psi, write a messagte to qtapp
+    the message should be displayed in the commandline
