+
+## Installation
+You can also install js-md2 by using Bower.
+
+    bower install js-md2
+
 For node.js, you can use this command to install:
 
     npm install js-md2
 
 ## Usage
+You could use like this:
+```JavaScript
+md2('Message to hash');
+```
 If you use node.js, you should require the module first:
 ```JavaScript
 md2 = require('js-md2');
 ```
-And you could use like this:
+
-```JavaScript
+### Methods
-md2('Message to hash');
+
-```
+#### md2(str, asciiOnly)
+
+Hash string to md2, set asciiOnly to true for better performace if you ensure input is ascii.
+
+##### *str: `String`*
+
+String to hash.
+
+##### *asciiOnly: `Boolean` (default: `false`)*
+
+Specify the string encoding is ASCII.
