  <h3>Why LESS?</h3>
  <p>Bootstrap is made with LESS at its core, a dynamic stylesheet language created by our good friend, <a href="http://cloudhead.io">Alexis Sellier</a>. It makes developing systems-based CSS faster, easier, and more fun.</p>

  <h3>What's included?</h3>
  <p>As an extension of CSS, LESS includes variables, mixins for reusable snippets of code, operations for simple math, nesting, and even color functions.</p>

  <h3>Learn more</h3>
  <img style="float: right; height: 36px;" src="assets/img/less-logo-large.png" alt="LESS CSS">
  <p>Visit the official website at <a href="http://lesscss.org">http://lesscss.org</a> to learn more.</p>

  <h3><a href="#variables">Variables</a></h3>
  <p>Managing colors and pixel values in CSS can be a bit of a pain, usually full of copy and paste. Not with LESS though&mdash;assign colors or pixel values as variables and change them once.</p>

  <h3><a href="#mixins">Mixins</a></h3>
  <p>Those three border-radius declarations you need to make in regular ol' CSS? Now they're down to one line with the help of mixins, snippets of code you can reuse anywhere.</p>

  <h3>Operations</h3>
  <p>Make your grid, leading, and more super flexible by doing the math on the fly with operations. Multiply, divide, add, and subtract your way to CSS sanity.</p>

      <p>So, go ahead and use the existing ones or feel free to add your own as you need.</p>

  <h3>Node with makefile</h3>
  <p>Install the LESS command line compiler, JSHint, Recess, and uglify-js globally with npm by running the following command:</p>
  <pre>$ npm install -g less jshint recess uglify-js</pre>
  <p>Once installed just run <code>make</code> from the root of your bootstrap directory and you're all set.</p>
  <p>Additionally, if you have <a href="https://github.com/mynyml/watchr">watchr</a> installed, you may run <code>make watch</code> to have bootstrap automatically rebuilt every time you edit a file in the bootstrap lib (this isn't required, just a convenience method).</p>

  <h3>Command line</h3>
  <p>Install the LESS command line tool via Node and run the following command:</p>
    <pre>$ lessc ./less/bootstrap.less > bootstrap.css</pre>
  <p>Be sure to include <code>--compress</code> in that command if you're trying to save some bytes!</p>

  <h3>Javascript</h3>
  <p><a href="http://lesscss.org/">Download the latest Less.js</a> and include the path to it (and Bootstrap) in the <code>&lt;head&gt;</code>.</p>
