 A collection of CSS buttons.
 
+## About this project
+
 My goal was to create a variety of stylish buttons for the web, using minimal markup while taking advantage of the HTML5/CSS3 technologies.
 
-In short, buttons should never be dull!
+The collection includes 26 different button styles.
+
+Each style has been generated via a component-based system, using [SASS](http://sass-lang.com/) (a CSS preprocessor). The process is designed to make it easy and simple to create a new set of button styles in a modular fashion.
+
+Ultimately, the **markup** is the same for each set of button style:
+
+```html
+<button class="btn btn-primary">Button</button>
+```
+
+where class `.btn` is the generic component class and `.btn-primary` is the style-specific class.
+
+Leveraging the power of SASS [mixins](http://sass-lang.com/documentation/file.SASS_REFERENCE.html#mixins), each style is generated simply by taking a color as an input. For the `alpha` style, it looks like this:
+
+```scss
+// Assuming the color variable has been declared, like so:
+// $color-primary: #7AD84E
+.btn-primary { @include btn-alpha($color-primary); }
+```
+
+## Final thoughts
+
+Like any bit of UI, buttons should never be dull. Attention to detail is key in a design with sensibiilty.
