 Tiny but perfect jQuery scrollbar plugin
 
-Under Development!
+Why perfect-scrollbar?
 ------------------
 
-I'm working on... :D
+I worked on the personal project recently, and I was trying to find the jQuery scrollbar plugin that's *perfect*. But there was no *perfect* scrollbar plugin. That's why I decided to make one.
+
+perfect-scrollbar is very tiny but *perfect*(for me, and maybe for the most of developers) jQuery scrollbar plugin.  
+I hope you love this!
+
+Demo: http://noraesae.github.com/perfect-scrollbar/
+
+What means *perfect*?
+---------------------
+
+*perfect* means...
+
+* There should be no css change on any original element.
+* The scrollbar should not affect the original design layout.
+* The design of the scrollbar should be (nearly) fully customizable.
+* If the size of the container or the content changes, the scrollbar size and position should be able to change.
+
+Then perfect-scrollbar is really *perfect*?
+-------------------------------------------
+
+Yes! the only thing that's not *perfect* is my English.
+
+* perfect-scrollbar has some requirements, but doesn't change or add any style on original elements.
+* perfect-scrollbar is designed not to have width or height. It's fixed on the right and bottom side of the container.
+* You can change nearly all css styles of the scrollbar. The scrollbar design has no dependency on scripts.
+* perfect-scrollbar support 'update' function. Whenever you need to update the size or position of the scrollbar, just update.
+* Additionally, perfect-scrollbar do use 'scrollTop' and 'scrollLeft', not absolute position or something messy.
+
+It's cool, isn't it?
+
+Requirements
+------------
+
+To make this plugin *perfect*, some requirements were not avoidable. But they're all very trivial and there's nothing to worry about.
+
+* there must be the *one* content element(like div) for the container.
+* the container must have a 'position' css style.
+* the scrollbar's position must be 'absolute'.
+* the scrollbar-x must have a 'bottom' css style, and the scrollbar-y must have a 'right' css style.
+ 
+Optional parameters
+-------------------
+
+perfect-scrollbar supports optional parameters.
+
+### wheelSpeed
+The scroll speed applied to mousewheel event.  
+Default: 10
+
+### wheelPropagation
+If this option is true, when the scroll reach the end of the side, mousewheel event will be propagated to parent element.  
+Default: false
+
+
+How to Use
+----------
+
+```html
+<style>
+  #Demo { position: 'relative'; }
+</style>
+<div id='Demo'>
+  <div>
+    ...
+  </div>
+</div>
+```
+When the html document is like above, just use like this:
+```javascript
+$('#Demo').perfectScrollbar();
+```
+
+With optional parameters:
+```javascript
+$("#Demo").perfectScrollbar({
+  wheelSpeed: 20,
+  wheelPropagation: true
+})
+```
+
+If the size of your container or content changes:
+```javascript
+$('#Demo').perfectScrollbar('update');
+```
+If you want to destory the scrollbar:
+```javascript
+$('#Demo').perfectScrollbar('destroy');
+```
+
+If you want to scroll to somewhere, just use scroll-top css and update.
+```javascript
+$("#Demo").scrollTop(0);
+$("#Demo").perfectScrollbar('update');
+```
+
+Very helpful friends
+--------------------
+
+perfect-scrollbar supports [jquery-mousewheel](https://github.com/brandonaaron/jquery-mousewheel). If you want to use mousewheel features, please include jquery-mousewheel before using perfect-scrollbar.
+
+If you want to make this plugin's update function more responsive, [jquery-resize](https://github.com/cowboy/jquery-resize) can be helpful.
+
+Contribution
+------------
+
+I *really* welcome contributions! Please feel free to fork and issue pull requests when...
+
+* You have a very nice idea to improve this plugin!
+* You found a bug!
+* You're good at English and can help my bad English!
+
+Also you can just open issues, and I can look into them.
