Let's get on with it!

##Installation

###Step 1: Link required files

First and most important, the jQuery library needs to be included (no need to download - link directly from Google). Next, download the package from this site and link the bxSlider CSS file (for the theme) and the bxSlider Javascript file.

```html
<!-- jQuery library (served from Google) -->
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<!-- bxSlider Javascript file -->
<script src="/js/jquery.bxslider.min.js"></script>
<!-- bxSlider CSS file -->
<link href="/lib/jquery.bxslider.css" rel="stylesheet" />
```

###Step 2: Create HTML markup

Create a `<ul class="bxslider">` element, with a `<li>` for each slide. Slides can contain images, video, or any other HTML content!

```html
<ul class="bxslider">
  <li><img src="/images/pic1.jpg" /></li>
  <li><img src="/images/pic2.jpg" /></li>
  <li><img src="/images/pic3.jpg" /></li>
  <li><img src="/images/pic4.jpg" /></li>
</ul>
```

###Step 3: Call the bxSlider

Call .bxslider() on `<ul class="bxslider">`. Note that the call must be made inside of a $(document).ready() call, or the plugin will not work!

```javascript
$(document).ready(function(){
  $('.bxslider').bxSlider();
});
```

## Changelog

### Version 4.1.2
* Added `bower.json` configuration file. Manage bxSlider as a dependency using [bower](http://bower.io/).

### Version 4.1.1
* Removed imagesLoaded library and added iframe preloading support
* Added responsive option - setting to false will prevent $(window).resize binding

### Version 4.1
* Carousel mode (minSlides / maxSlides) was re-written to be more intuitive.
* SlideWidth now acts as it should (slides respect the width value).
* SlideWidth now properly parsed: accepts string ("600px") or integer (600).
* Slider now only needs to load visible slides (by default) in order to initialize which results in much faster loading. A "preloadImages" setting allows for configuration.


Long live Zep.
