 # js-sha1
 This is a simple SHA1 hash function for JavaScript supports UTF-8 encoding.

+## Install
+For node.js, you can use this command to install:
+
+    npm install js-sha1
+
 ## Usage
+If you use node.js, you should require the module first:
+
+    var sha1 = require('js-sha1');
+
+And you could use like this:
+
    sha1('Message to hash');

 ## Example
