+# Highlight.js
+
+[![Build Status](https://travis-ci.org/isagalaev/highlight.js.svg?branch=master)](https://travis-ci.org/isagalaev/highlight.js)
+
+Highlight.js is a syntax highlighter written in JavaScript. It works in the
+browser as well as on the server. It works with pretty much any markup,
+doesn't depend on any framework and has automatic language detection.
+
+
+## Getting Started
+
+The bare minimum for using highlight.js on a web page is linking to the library
+along with one of the styles and calling [`initHighlightingOnLoad`][1]:
+
+```html
+<link rel="stylesheet" href="/path/to/styles/default.css">
+<script src="/path/to/highlight.pack.js"></script>
+<script>hljs.initHighlightingOnLoad();</script>
+```
+
+This will find and highlight code inside of `<pre><code>` tags trying to detect
+the language automatically. If automatic detection doesn't work for you, you can
+specify the language in the class attribute:
+
+```html
+<pre><code class="html">...</code></pre>
+```
+
+The list of supported language classes is available in the [class reference][8].
+Classes can also be prefixed with either `language-` or `lang-`.
+
+To disable highlighting altogether use the `nohighlight` class:
+
+```html
+<pre><code class="nohighlight">...</code></pre>
+```
+
+## Custom Initialization
+
+When you need a bit more control over the initialization of
+highlight.js, you can use the [`highlightBlock`][2] and [`configure`][3]
+functions. This allows you to control *what* to highlight and *when*.
+
+Here's an equivalent way to calling [`initHighlightingOnLoad`][1] using jQuery:
+
+```javascript
+$(document).ready(function() {
+  $('pre code').each(function(i, block) {
+    hljs.highlightBlock(block);
+  });
+});
+```
+
+You can use any tags instead of `<pre><code>` to mark up your code. If you don't
+use a container that preserve line breaks you will need to configure
+highlight.js to use the `<br>` tag:
+
+```javascript
+hljs.configure({useBR: true});
+
+$('div.code').each(function(i, block) {
+  hljs.highlightBlock(block);
+});
+```
+
+For other options refer to the documentation for [`configure`][3].
+
+
+## Getting the Library
+
+You can get highlight.js as a hosted or custom-build browser script or as a
+server module. Head over to the [download page][4] for all the options.
+
+Note, that the library is not supposed to work straight from the source on
+GitHub, it requires building. If none of the pre-packaged options work for you
+refer to the [building documentation][5].
