+### Single player

 You can play single mode by launching any file `Q_HumainVs<AI name><tree depth><variant>.py` where _AI name_ is the name of the IA you have to combat, _tree depth_ the number of turns the AI will explore, and _variant_ is a marker meaning that the function used to evaluate the strength of a situation has been tweaked.
 
 For instance : *Q_HumainVsAlphaBeta3+.py* means that you will fight an AI using the **Alpha Beta** algorithm, exploring the game **3** turns in the future, and using a variant **+** of the evaluation function.

+### Multiplayer
+
+You can oppose another human being by launching the `Q_HumainVsHumain.py` python script.
