+
+## Installation
+You can also install js-sha256 by using Bower.
+
+    bower install js-sha256
+
+For node.js, you can use this command to install:
+
+    npm install js-sha256
+
+## Usage
+You could use like this:
+```JavaScript
+sha256('Message to hash');
+sha224('Message to hash');
+
+var hash = sha256.create();
+hash.update('Message to hash');
+hash.hex();
+
+var hash2 = sha256.update('Message to hash');
+hash2.update('Message2 to hash');
+hash2.array();
+
+// HMAC
+sha256.hmac('key', 'Message to hash');
+sha224.hmac('key', 'Message to hash');
+
+var hash = sha256.hmac.create('key');
+hash.update('Message to hash');
+hash.hex();
+
+var hash2 = sha256.hmac.update('key', 'Message to hash');
+hash2.update('Message2 to hash');
+hash2.array();
+```
+If you use node.js, you should require the module first:
+```JavaScript
+var sha256 = require('js-sha256');
+```
+or 
+```JavaScript
+var sha256 = require('js-sha256').sha256;
+var sha224 = require('js-sha256').sha224;
+```
+It supports AMD:
+```JavaScript
+require(['your/path/sha256.js'], function(sha256) {
+// ...
+});
+```
+or TypeScript
+```TypeScript
+import { sha256, sha224 } from 'js-sha256';
+```
+## Example
+```JavaScript
+sha256(''); // e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855

+
+// It also supports UTF-8 encoding
+sha256('中文'); // 72726d8818f693066ceb69afa364218b692e62ea92b385782363780f47529c21
