-### DeepBlue.py
+# DeepBlue.py
 
+DeepBlueCLI, ported to Python. Designed for parsing evtx files on Unix/Linux.
+
+## libevtx
+
+Requires libevtx:  https://github.com/libyal/libevtx
+
+## Other evtx frameworks
+
+Note that I tested a few Unix/Linux/Python evtx frameworks. 
+
+This is quite popular: https://github.com/williballenthin/python-evtx
+
+I ran into trouble with *some* .evtx files, where it would crash with this error:
+
+```
+UnicodeDecodeError: 'utf16' codec can't decode bytes in position 0-1: illegal UTF-16 surrogate
+```
+
+I found libevtx 'just worked', and had the added benefit of both Python and compiled options.
