-# linter-lua package
+linter-lua
+===========
 
-This package no yet ready.
+> luac — The luac program parses lua files. It can be used for detecting errors in lua code. See [http://www.lua.org/manual/4.0/luac.html](http://www.lua.org/manual/4.0/luac.html) for more informations about luac.
+
+This package will lint your `.lua` opened files in Atom through luac.  **It will lint on edit and/or save**, so you'll see instantly if your code has errors.
+
+Due to the way that luac works it will only notify you of the first error found in the file.
+
