 Please create an issue if something doesn't work or if there is a browser specific bug. I'll try to fix it as soon as possible. Please send me your Pull requests if you have a nice solution! I'm also going to review old issues in balupton's repository and try to solve them too.

 - Provide a forwards-compatible experience for HTML4 States to HTML5 States (so if a hash-fallbacked url is accessed by a HTML5 browser it is naturally transformed into its non-hashed url equivalent)
 - Provide support for as many javascript frameworks as possible via adapters; especially [Dojo](http://dojotoolkit.org/), [ExtJS](http://www.sencha.com/), [jQuery](http://jquery.com/), [MooTools](http://mootools.net/), [Right.js](http://rightjs.org/) and [Zepto](http://zeptojs.com/).

-To ajaxify your entire website with the HTML5 History API, History.js and jQuery the [Ajaxify Script](https://github.com/browserstate/ajaxify) is all you need. It's that easy.
+### Via Ajaxify Script
+To ajaxify your entire website with the HTML5 History API, History.js and jQuery the [Ajaxify script](https://github.com/browserstate/ajaxify) is all you need. It's that easy.
 
-### Ruby On Rails
+### Via Ajaxify Extension
+If you don't have access to your server, or just want to try out the Ajaxify script first, you can install the [History.js It! Google Chrome Extension](https://github.com/browserstate/historyjsit.crx) to try out History.js via Ajaxify on select websites without actually installing History.js/Ajaxify on your server.
 
+### Via Ruby On Rails Gem
 If you are using Rails, then the easiest way for you to try History.js would be to use [Wiselinks](https://github.com/igor-alexandrov/wiselinks) gem. Wiselinks integrates  into Rails application and allows you to start using History.js with three lines of code.

 ### What's the deal with the SUIDs used in the HTML4 States?
 
 - SUIDs (State Unique Identifiers) are used when we utilise a `title` and/or `data` in our state. Adding a SUID allows us to associate particular states with data and titles while keeping the urls as simple as possible (don't worry it's all tested, working and a lot smarter than I'm making it out to be).

 ### Is there a working demo?
 
 - Sure is, give it a download and navigate to the demo directory in your browser :-)
 - If you are after something a bit more adventurous than a end-user demo, open up the tests directory in your browser and editor - it'll rock your world and show all the vast use cases that History.js supports.
