 First, some definitions of terms and concepts I will use in '''pKNyX'''. They are the summary of my undersanding of the KNX specifications.
 
-Unlike other standards, KNX is build arround the concept of ''Distributed Application''. An application is split up into several '''Functional Blocks''', which can themselves be implemented in different '''Devices''' in the KNX network. A Functional Block communicates over the bus through its '''Datapoints'''.

+Unlike other standards, KNX is build arround the concept of ''Distributed Applications''. An application is split up into several '''Functional Blocks''', which can themselves be implemented in different '''Devices''' in the KNX network.
+
+A Functional Block communicates over the bus through its '''Datapoints'''. A Datapoint can be an '''input''', an '''output''' or a '''parameter'''. For the real communication, a Datapoint can be implemented as '''Group Object''', '''Interface Object Property''', '''Polling Value''' or '''Memory Mapping'''. The most usefull is of course the Group Object.
+
+To be able to communicate, Datapoints must have some well defined types, named '''Datapoint Types'''. These standardized Datapoint Types ensure the compatibility of the different devices made from many manufacturers. This another key point of the KNX bus.
+
+'''pKNyX''' tries to follow as much as possible the KNX specifications in its implementation. This may not leads to the best architecture in term of efficiency, but I think it is the best way to have something easy to understand, maintain and improve. This can also  serve as a summary of all informations I can grab arround these specs.
