+# Code Climate luacheck Engine
+
+CodeClimate Engine that runs [luacheck](https://github.com/mpeterv/luacheck/) on Lua files.
+Uses [linguist](https://github.com/github/linguist) to detect Lua files.
+
+## Testing
+
+```shell
+make build test
+```
+
+## TODO
+
+- [ ] expose luacheck options via to codeclimate
+- [ ] fingerprinting
+- [ ] detect categories
