+# kuler
+
+Kuler is small and nifty node module that allows you to create terminal based
+colors using hex color codes, just like you're used to doing in your CSS. We're
+in a modern world now and terminals support more than 16 colors so we are stupid
+to not take advantage of this.
+
+## Installation
+
+The package is released in the public npm registry and can be installed by
+running:
+
+```
+npm install --save kuler
+```
+
+## Usage
+
+To color a string simply pass it the string you want to have colored as first
+argument and the color as hex as second argument:
+
+```js
+'use strict';
+
+const kuler = require('kuler');
+const str = kuler('foo', '#FF6600');
+```
+
+The color code sequence is automatically terminated at the end of the string so
+the colors do no bleed to other pieces of text. So doing:
+
+```js
+console.log(kuler('red', '#F00'), 'normal');
+```
+
+Will work without any issues.
