 # linter-flint
-Lint projects using `flint`
 
-You can find flint [here](https://github.com/pengwynn/flint).
+Lint projects using [`flint`][flint].
+
+# Installation
+
+You need to have [`flint`][flint] installed on your system before using this
+package. Once that is setup this package should work right away. If you are
+getting messages about `flint` not being available you may need to set the full
+path to it in your settings.
+
+As this package is just a wrapper around `flint`, you will need something to
+actually run it. By default the [Linter][] package will be installed for you to
+fill this need.
+
+
+[flint]: https://github.com/pengwynn/flint
