+# `srcdoc` polyfill
+
+HTML5 defines a new attribute for iFrames named `srcdoc`. This attribute allows
+developers to specify an iFrame's content in-line with the iFrame itself. For
+instance:
+
+ <iframe srcdoc="<html><body>Hello, <b>world</b>.</body></html>"></iframe>
+
+As of June 2012, this feature is not available in any (stable) browsers.
+Fortunately, most of today's browsers support similar functionality through
+script-targeted URLs, i.e.
+
+ <iframe src="javascript: '<html><body>Hello, <b>world</b>.</body></html>'"></iframe>
+
+For more on `srcdoc`, see [the WhatWG specification](http://www.whatwg.org/specs/web-apps/current-work/multipage/the-iframe-element.html#attr-iframe-srcdoc) and [this post on
+Bocoup.com](http://weblog.bocoup.com/third-party-javascript-development-future/).
+
+## Usage
+
+By including the script at the bottom of the document `<body>`, any available
+iFrames which declare a `srcdoc` attribute attribute) will receive this
+"shimmed" behavior. (In browsers that already implement this functionality, no
+change will take place.)
+
+The shim also defines a `srcDoc` variable in the global scope:
+
+* `srcDoc.set( iframe [, content] )` - sets the content of the provided iFrame
+ element using the `srcdoc` attribute where available (falling back on a
+ script-targeted URL in non-supporting browsers). The desired content of the
+ iFrame may optionally be specified. If blank, the current value of the
+ element's `srcdoc` attribute will be referenced for content.
+* `srcDoc.noConflict()` - Sets the value of the global `srcDoc` variable to its
+ original value. Returns the `srcDoc` object defined by this project for
+ re-aliasing.
+
+## Browser Support
+
+Tested in the following browsers:
+
+* Microsoft Internet Explorer
+ * 6, 7, 8, 9, 10.0.8102.0 (developer preview)
+* Safari
+ * 4, 5.0, 5.1
+* Google Chrome
+ * 14, 15, 16, 17, 18, 19, 20
+* Opera
+ * 11.1, 11.5, 11.6, 12 (beta)
+* Mozilla FireFox
+ * 3.6, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 (beta)
+
+The following browsers are *not* supported:
+
+* Opera 10.0
+
+## Building
+
+The build process for this project is written with
+[Grunt.js](http://gruntjs.com). Please refer to the grunt documentation for
+details on installing grunt.
+
+## Tests
+
+The shim's tests are written in QUnit, and can be run by visiting the
+`test/index.html` file in the browser, or by running `grunt qunit` from the
+command line.
