 and it uses few external libraries.

+### Paradox alarm panels:
+
+At the moment only MG5050 panel is fully supported as it's the one i own.
+
+To make other panels works you need to compile the panel registers file in 
+penguidom/plugins/paradox/panels/ like the MG5050.py one.
+
+To make this easier, you can "sniff" the protocol communication between the panel and
+a client side software like babyware or winload by installing them inside a virtual machine
+( i use virtualbox for that ) and then attach the serial over TCP using the included serial proxy
+in the paradox module.
