+Contributors: GaryJ

+Tags: genesis, js-no-js
+Requires at least: 3.0
+Tested up to: 3.3
+Stable tag: 1.0.1
+
+Make front-end styling easier for child themes on the Genesis Framework based on whether JavaScript is enabled or not.
+
+== Description ==
+
+Make front-end styling easier for child themes on the <a href="http://genesis-theme-framework.com/">Genesis Framework</a> based on whether JavaScript is enabled or not.
+
+Adds a `no-js` body class to the front-end, and a script on `genesis_before` which immediately changes the class to `js` if JavaScript is enabled.
+This is how WP does things on the back-end, to allow different styles for the same elements depending if JavaScript is active or not.
+
+This plugin is only useful if you're using a child theme of the <a href="http://genesis-theme-framework.com/">Genesis Framework</a> since it needs to use the `genesis_before` hook.
+
+== Installation ==
+
+1. Unzip and upload `genesis-js-no-js` folder to the `/wp-content/plugins/` directory
+1. Activate the plugin through the 'Plugins' menu in WordPress
+
+== Frequently Asked Questions ==
+
+= What does this plugin actually do? =
+
+If you look at the source of a WordPress back-end page, you'll see it has a body class of `no-js`. Immediately after the opening `body` tag is a small script which replaces `no-js` with `js` (you can see the amended class with Firebug / Inspector).
+
+WordPress uses this to apply different styles to the same elements, depending on whether JavaScript is present or not.
+
+This plugin recreates the same effect, but for the front-end of <a href="http://genesis-theme-framework.com/">Genesis Framework</a> child themes.
+
+= Shouldn't the script be at the end of the page? =
+
+Usually, yes, but it's a fairly small script, so does not block rendering of other content for any noticeable length of time.
+
+Doing it immediately also reduces a flash of incorrectly styled content, as the page does not load with `no-js` styles, then switch to `js` once everything has finished loading.
+
+== Changelog ==
+
+= 1.0.1 =
+* Improved plugin so script is hooked in with priority 1 - avoids a theme placing anything before the script (props [Josh Stauffer](http://twitter.com/joshstauffer))
+
+= 1.0 =
+* First public version.
+
+== Upgrade Notice ==
+
+= 1.0.1 =
+Minor change to avoid potential problems with themes hooking in elements before the script.
+
+= 1.0 =
+Update from nothingness. You will feel better for it.
