This library implements the Glicko2 algorithm (http://www.glicko.net/glicko/glicko2.pdf), which provides a rating system for 2 player games.
This library is composed of a pre-instanciated module you can use out of the box, and a functor which allows you to configure certain variables of the algorithm.

For first time users, or if all you need is a library which helps you rate games, one game at a time, look into the single game module.
If you need to take advantage of the rating periods, you will need to look into the low level module.
If you need to configure the low level variables of the Glicko2 algorith, you might want to use provided functor.
