+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.
 
+The requirement below is for perfect-scrollbar <= 0.3.4
+
+* there must be the *one* content element(like div) for the container.
+ 
+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**
+
+### minScrollbarLength
+When set to an integer value, the thumb part of the scrollbar will not shrink below that number of pixels.  
+**Default: null**
+
+### useBothWheelAxes
+When set to true, and only one (vertical or horizontal) scrollbar is visible then both vertical and horizontal scrolling will affect the scrollbar.  
+**Default: false**
+
+### useKeyboard
+When set to true, the scroll works with arrow keys on the keyboard. The element is scrolled only when the mouse cursor hovers the element.  
+**Default: true**
+
+### suppressScrollX
+When set to true, the scroll bar in X axis will not be available, regardless of the content width.  
+**Default: false**
+
+### suppressScrollY
+When set to true, the scroll bar in Y axis will not be available, regardless of the content height.  
+**Default: false**
+
+### scrollXMarginOffset
+The number of pixels the content width can surpass the container width without enabling the X axis scroll bar. Allows some "wiggle room" or "offset break", so that X axis scroll bar is not enabled just because of a few pixels.  
+**Default: 0**
+
+### scrollYMarginOffset
+The number of pixels the content height can surpass the container height without enabling the Y axis scroll bar. Allows some "wiggle room" or "offset break", so that Y axis scroll bar is not enabled just because of a few pixels.  
+**Default: 0**

 Contribution

+#### Please read [Contributing](https://github.com/noraesae/perfect-scrollbar/wiki/Contributing) in the wiki before making any contibution.
+
+
 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.
+For IE problems, please refer to [IE Support](https://github.com/noraesae/perfect-scrollbar#ie-support)
+
+IE Support
+----------
+
+This plugin supports old IE browsers in the **minimum** range. The plugin is tested in IEs >= IE6 and works(not well, but works).
+
+**But the project will not accept the patches to fix IE problems in IE 6/7/8.**
+
+From jQuery 2.0, jQuery also will not support IE 6/7/8. I also think that supporting old browsers really breaks the web development conventions.
+
+When old IEs should be supported, please fork the project and make patches personally.
