   1. Copy the normalize-scss files to your sass directory so that you can alter it
     as you include it in your project. To aid with this method, normalize-scss
     includes several ready-made "fork" versions:
-    * fork-versions/default - Fork for libSass / Ruby Sass
+    * [fork-versions/default](fork-versions/default) - Fork for libSass or Ruby Sass
     * [fork-versions/ruby-sass-compass](fork-versions/ruby-sass-compass) - Fork for Ruby Sass with Compass
-    * fork-versions/typey - Fork for node-sass with Typey
-    * fork-versions/typey-kss - Fork for node-sass with Typey and KSS comments
+    * fork-versions/typey - Fork with Typey
+    * fork-versions/typey-kss - Fork with Typey and KSS comments
   2. The normalize-scss code uses the `support-for` module, so add it
 
 __Approach 2:__ Install and include normalize-scss untouched and then build upon it, overriding the defaults later in your Sass when necessary. Just import normalize-scss like any normal Sass module by:

+# Fork-able normalize-scss<br> for libSass or Ruby Sass
+
+## Using with node-sass
+
+1. Copy these files to your Sass project.
+2. This fork-able version requires the [support-for](https://github.com/JohnAlbin/support-for) Sass module. Add it to your package.json with: `npm install --save-dev support-for`
+3. Add support-for's `sass` directory to your nodeSass' [`includePaths` option](https://github.com/sass/node-sass#includepaths).
+
+ ```js
+var sass = require('node-sass'),
+  path = require('path');
+
+sass.render({
+  file: scss_filename,
+  includePaths: [
+    path.join(__dirname, 'node_modules/support-for/sass')
+  ]
+}, function(err, result) { /*...*/ });
+```
+
+## Using with libSass
+
+If you are not using node-sass with libSass, you probably already know how to include 3rd party libraries into your Sass project.
+
+1. Copy these files to your Sass project.
+2. This fork-able version requires the [support-for]() Sass module. Add support-for's `sass` directory to your libSass include paths in the "usual way".
+
+## Using with Ruby Sass
+
+In addition to copying these files to your Sass project, you'll also need to:
+
+1. Edit your `Gemfile` file to add:
+
+ ```ruby
+gem 'support-for', '~> 1.0'
+```
+
+2. If you use Compass, edit your `config.rb` file to add:
+
+ ```ruby
+require 'support-for'
+```
+
+3. Update your local Gems with: `bundle install`
