 ===== Usage Tips =====
-For ESSIDs which contain spaces, put the ESSID in quotes: 'this contains spaces'.
+==== WPA/WPA2 Requirements ====
+The capture file must contain a valid four-way handshake.  For this purpose having (packets 2 and 3) or (packets 3 and 4) will work correctly.  In fact, you don't truly need all four handshake packets.
+As well, only data packets following the handshake will be decrypted.  This is because information is required from the handshake in order to decrypt the data packets.
