-texty
+# texty
+An extremely simple text-adventure game engine(?)
+
+## What is this?
+I was bored
+
+## How do I make a game
+Check out the `example.yml` file, all games are in the `YAML` format.
+
+## How do I use this
+Download/clone the repo and run the `__main__.py` file with the path to a game in `YAML` format as the first argument.
+
+## TODO
+- Colors
+- Catching errors while parsing YAML
+- Maybe a welcome screen instead of the need to enter the path as argument
