          <h1>Built with LESS</h1>
        </div>

        <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>

      <!-- COMPILING LESS AND BOOTSTRAP
      ================================================== -->
      <section id="compiling">
        <div class="page-header">
          <h1>Compiling Bootstrap with LESS</h1>
        </div>
        <div class="alert alert-info">
          <strong>Note:</strong> If you're submitting a pull request to GitHub with modified CSS, you <strong>must</strong> recompile the CSS via any of these methods.
        </div>

        <h2>Tools for compiling</h2>

        <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>
<pre class="prettyprint">
&lt;link rel="stylesheet/less" href="/path/to/bootstrap.less"&gt;
&lt;script src="/path/to/less.js"&gt;&lt;/script&gt;
</pre>
        <p>To recompile the .less files, just save them and reload your page. Less.js compiles them and stores them in local storage.</p>

        <h3>Unofficial Mac app</h3>
        <p><a href="http://incident57.com/less/">The unofficial Mac app</a> watches directories of .less files and compiles the code to local files after every save of a watched .less file.</p>
        <p>If you like, you can toggle preferences in the app for automatic minifying and which directory the compiled files end up in.</p>

        <h3>More Mac apps</h3>
        <h4><a href="http://crunchapp.net/" target="_blank">Crunch</a></h4>
        <p>Crunch is a great looking LESS editor and compiler built on Adobe Air.</p>
        <h4><a href="http://incident57.com/codekit/" target="_blank">CodeKit</a></h4>
        <p>Created by the same guy as the unofficial Mac app, CodeKit is a Mac app that compiles LESS, SASS, Stylus, and CoffeeScript.</p>
        <h4><a href="http://wearekiss.com/simpless" target="_blank">Simpless</a></h4>
        <p>Mac, Linux, and PC app for drag and drop compiling of LESS files. Plus, the <a href="https://github.com/Paratron/SimpLESS" target="_blank">source code is on GitHub</a>.</p>
