 > Ajax website engine for [better-dom](https://github.com/chemerisuk/better-dom)
 
 The library helps to solve one of the most important problem for a typical website: improving performance. There is a term called "Full AJAX" that means a library that makes a regular HTTP links or forms to be AJAXified. After including the library on page and simple adaptation on backend each navigation change triggers an partial page reload which is always faster than full page refresh and allows to save a use state on client side as well.

-## Determine strategy for browser history
-There are two main strategies that allows you to work with browser history (so back/forward buttons will work properly): using [HTML5 History API](https://developer.mozilla.org/en/docs/DOM/Manipulating_the_browser_history) (`better-ajaxify-pushstate.js`) or via __hashchange__ event (`better-ajaxify-hashchange.js`). Each has it's own advantages and disadvantages.
-
-### HTML5 History API
-
-__Pros__:
-+ performance: initial page load always takes a single request 
-+ clear and SEO-friendly address bar urls
-+ you can use archors on your page as in regular case
-
-__Cons__:
-- there are some quirks in several old implementations (but all of them are solved in modern browsers)
-- some old browsers do [not support the HTML5 History API](http://caniuse.com/#search=push). Also early Android 4 has [lack of support](https://code.google.com/p/android/issues/detail?id=23979) as well.
-
-### `hashchange` event
-
-__Pros__:
-+ [great and consistent support](http://caniuse.com/#search=hashchange) in all browsers
-
-__Cons__:
-- urls have to start with `#` that looks weird and is not a SEO-frieldly
-- internal page loading takes two requests instead of single one (there are some tricks to avoid that in some cases but in general the rule is truthy)
-- you should put anchors carefully because they used for page navigation as well
-
 ## Frontend setup
+Starting from version 1.7 only [HTML5 History API](https://developer.mozilla.org/en/docs/DOM/Manipulating_the_browser_history) is supported to manage browser history.
 
 ### Custom events
 The library exposes several custom events for advanced interaction.
