+# Make mids.db
+
+Licensed under [GNU GPL v3](../../../LICENSE)
+
+Python3 script creates a MID (Marine Identification Digit) database.
+MID is part of MMSI and determines (among other things) the conutry. 
+
+
+USAGE:
+ - Copy Excel file from https://www.itu.int/en/ITU-R/terrestrial/fmd/Pages/mid.aspx
+ - Convert it to a csv document
+ - Run Python 3 script: `./make_mids_db.py` 
+ - Copy file to /AIS folder on SDCARD
