Standing on the foreheads of giants (namely Paul Irish and Divya Manian and 
the good folks that have helped them create and continue the growth of HTML5 Boilerplate, 
I present to you my first WordPress plug-in, HTML5 Boilerplate. As a spin-off of my 
Boilerplate – Starkers WP Theme, this plug-in can be added to any theme, new, pre-existing, 
already customized, whatevs!
The clumsiest part of this is dealing with the Boilerplate CSS and JS files. 
To avoid any changes you make from being overwritten during upgrades, 
“starter” files have been created in the <code>/css</code> and <code>/js</code> directories. I recommend 
creating copies of the starter files (removing ‘-starter’ from the new filenames) 
that you can safely edit. That way, if the starter files are updated later, you can 
simply copy/paste from them into your files again, and all is fine.
Another route would be to add additional links in your pages, but this does increase 
your HTTP Requests, which hurts performance… 
Your call, let me know if you can think of a better implementation.

I also built a Boilerplate theme based on Elliot Jay Stocks’ Starkers Theme that can be found at:

This plugin provides a shortcode that when inserted will display the body from a referenced “boilerplate.” A boilerplate is a special post type defined by this plugin. References can be made by title, path or ID. Below is a list of shortcode attributes used by the boilerplate shortcode. Examples are given for hypothetical “Copyright” and “Payment Terms.” All attributes are optional except one of “byid“, “bypath” or “bytitle” must be specified:
<ul>
<li>
bytitle: The full case-sensitive title of the boilerplate, i.e. “Copyright” or “Payment Terms“
</li>
<li>
bypath: The editable lowercase path for the boilerplate, i.e. “copyright” or “payment-terms” (vs. “/boilerplates/copyright/” or “/boilerplates/payment-terms/“)
</li>
<li>
byid: Refers to the internal ID from the wp_posts table for the boilerplate post, i.e. 234 or 1273
</li>
<li>
showtitle: “true” or “false” (defaults to “false“); if “true” boilerplate content will be prefixed with the title of the boilerplate as entered in the edit screen, or optionally with a “title” attribute you specify.
</li>
<li>
title: Use to override the displayed title of the boilerplate in specific cases. When “title” is specified “showtitle” is implicity set to “true.”
</li>
<li>
titletag: HTML element used to wrap the title when “showtitle” is explicity “true” or “title” is set (defaults to “h3.”)
</li>
<li>
id: The HTML “id” attribute applied to the div element that wraps the boilerplate and it’s optional title. If not specificed the div will not get have an “id” set.
</li>
<li>
class: The HTML “class” attribute applied to the div& element that wraps the boilerplate and it’s optional title (defailts to “boilerplate.”)
</li>
</ul>
