+    \class Frame
+    The class Frame is responsible for reading, validating and interpreting frames from a websocket.
+    It reads data from a QIODevice, validates it against RFC 6455, and parses it into a frame (data, control).
+    Whenever an error is detected, the isValid() returns false.
+
+    \note The Frame class does not look at valid sequences of frames. It processes frames one at a time.
+    \note It is the DataProcessor that takes the sequence into account.
