+# Maxman
+
+Maxman is a simple game inspired by classics such as `Pacman`, `Achtung, die Kurve!` (also known as `Zatacka`), and `Snake`.
+
+The basic goal is to grow by eating the food lying around until you're big enough to eat your competitors.
+
+
+## Getting started
+
+The game's requirements are listed in `Pipfile`, so you can just install them with `pipenv install`.
+To run the game after installing the requirements, use `pipenv run ./maxman.py`
+
+
+## Controls
+
+Per default, each player has their own key bindings (up, left, down, right):
+* Maxman (yellow): `w`, `a`, `s`, `d`
+* Blackman (black): `i`, `j`, `k`, `l`
+
+Other key bindings are:
+* `SPACE`: Pause/resume
+
+
+## Playing against AI
+
+If you want to play against the AI instead of other players, supply the corresponding CLI flag: `pipenv run ./maxman.py --ai <number of AI players>`
