 ## itb-ranking
 
+This project runs parallel to the Minetest ITB server and processes the `points`
+table in `itb.sqlite`. It creates weighted ranks for players, builders and boxes
+and outputs JSON data. The current ITB website ingests this data and displays
+it.
+
+The points data is very, very large, and will continue to grow over time. For this
+reason there is an out-of-MT process doing this. Doing this in lua would require
+too much memory and CPU time. Currently, it takes a few minutes to run this task.
+
+## License
+
+The code is licensed MIT. It is technically trivial code, the mathmatics are very
+simple and there isn't much to it.
