+# Highlight.js
+
+Highlight.js highlights syntax in code examples on blogs, forums and,
+in fact, on any web page. It's very easy to use because it works
+automatically: finds blocks of code, detects a language, highlights it.
+
+Autodetection can be fine tuned when it fails by itself (see "Heuristics").
+
+
+## Basic usage
+
+Link the library and a stylesheet from your page and hook highlighting to
+the page load event:
+
+```html
+<link rel="stylesheet" href="styles/default.css">
+<script src="highlight.pack.js"></script>
+<script>hljs.initHighlightingOnLoad();</script>
+```
+
+This will highlight all code on the page marked up as `<pre><code> .. </code></pre>`.
+If you use different markup or need to apply highlighting dynamically, read
+"Custom initialization" below.
+
+- You can download your own customized version of "highlight.pack.js" or
+  use the hosted one as described on the download page:
+  <http://highlightjs.org/download/>
+
+- Style themes are available in the download package or as hosted files.
+  To create a custom style for your site see the class reference in the file
+  [CSS classes reference][cr] from the downloaded package.
+

+
+
+## node.js
+
+Highlight.js can be used under node.js. The package with all supported languages is
+installable from NPM:
+
+    npm install highlight.js
+
+Alternatively, you can build it from the source with only languages you need:
+
+    python3 tools/build.py -tnode lang1 lang2 ..
+
+Using the library:
+
+```javascript
+var hljs = require('highlight.js');
+
+// If you know the language
+hljs.highlight(lang, code).value;
+
+// Automatic language detection
+hljs.highlightAuto(code).value;
+```
+
+
+## AMD
+
+Highlight.js can be used with an AMD loader.  You will need to build it from
+source in order to do so:
+
+```bash
+$ python3 tools/build.py -tamd lang1 lang2 ..
+```
+
+Which will generate a `build/highlight.pack.js` which will load as an AMD
+module with support for the built languages and can be used like so:
+
+```javascript
+require(["highlight.js/build/highlight.pack"], function(hljs){
+
+  // If you know the language
+  hljs.highlight(lang, code).value;
+
+  // Automatic language detection
+  hljs.highlightAuto(code).value;
+});
+```
+
+
+## Tab replacement
+
+You can replace TAB ('\x09') characters used for indentation in your code
+with some fixed number of spaces or with a `<span>` to give them special
+styling:
+
+```html
+<script type="text/javascript">
+  hljs.configure({tabReplace: '    '}); // 4 spaces
+  // ... or
+  hljs.configure({tabReplace: '<span class="indent">\t</span>'});
+
+  hljs.initHighlightingOnLoad();
+</script>
+```
+
+## Custom initialization
+
+If you use different markup for code blocks you can initialize them manually
+with `highlightBlock(code)` function. It takes a DOM element containing the
+code to highlight and optionally a string with which to replace TAB
+characters.
+
+Initialization using, for example, jQuery might look like this:
+
+```javascript
+$(document).ready(function() {
+  $('pre code').each(function(i, e) {hljs.highlightBlock(e)});
+});
+```
+
+You can use `highlightBlock` to highlight blocks dynamically inserted into
+the page. Just make sure you don't do it twice for already highlighted
+blocks.
+
+If your code container relies on `<br>` tags instead of line breaks (i.e. if
+it's not `<pre>`) set the `useBR` option to `true`:
+
+```javascript
+hljs.configure({useBR: true});
+$('div.code').each(function(i, e) {hljs.highlightBlock(e)});
+```
+
+
+## Heuristics
+
+Autodetection of a code's language is done using a simple heuristic:
+the program tries to highlight a fragment with all available languages and
+counts all syntactic structures that it finds along the way. The language
+with greatest count wins.
+
+This means that in short fragments the probability of an error is high
+(and it really happens sometimes). In this cases you can set the fragment's
+language explicitly by assigning a class to the `<code>` element:
+
+```html
+<pre><code class="html">...</code></pre>
+```
+
+You can use class names recommended in HTML5: "language-html",
+"language-php". Classes also can be assigned to the `<pre>` element.
+
+To disable highlighting of a fragment altogether use "no-highlight" class:
+
+```html
+<pre><code class="no-highlight">...</code></pre>
+```
+
+
+## Export
+
+File export.html contains a little program that allows you to paste in a code
+snippet and then copy and paste the resulting HTML code generated by the
+highlighter. This is useful in situations when you can't use the script itself
+on a site.
