How to install Chili in 3 easy steps

site
Download and extract Chili's zip file SOMEWHERE into your site
page
Add the following lines to the HEAD of your page: 

<script type="text/javascript" src="SOMEWHERE/jquery.pack.js"></script>
<script type="text/javaScript" src="SOMEWHERE/chili.pack.js"></script>
<script type="text/javascript">
	ChiliBook.recipeFolder     = "SOMEWHERE/"; 
	ChiliBook.stylesheetFolder = "SOMEWHERE/"; 
</script>
code
Put your snippets inside CODE elements with a class like the language. The above snippet is in fact introduced in this page this way: 

<code class="html">
&lt;script type=&quot;text/javascript&quot; src=&quot;SOMEWHERE/jquery.pack.js&quot;&gt;&lt;/script&gt;
&lt;script type=&quot;text/javaScript&quot; src=&quot;SOMEWHERE/chili.pack.js&quot;&gt;&lt;/script&gt;
&lt;script type=&quot;text/javascript&quot;&gt;
	ChiliBook.recipeFolder     = &quot;SOMEWHERE/&quot;; 
	ChiliBook.stylesheetFolder = &quot;SOMEWHERE/&quot;; 
&lt;/script&gt;
</code>
The escaping is needed for introducing text into an HTML page. Use postable to make it as simple as possible.
