-sha256 = require('js-sha256');
+var sha256 = require('js-sha256');
 ```
 or
 ```JavaScript
-sha256 = require('js-sha256').sha256;

+### TypeScript
+If you use TypeScript, you can import like this:
+```TypeScript
+import { sha256, sha224 } from 'js-sha256';
+```
+### RequireJS
+It supports AMD:
+```JavaScript
+require(['your/path/sha256.js'], function(sha256) {
+// ...
+});
 ```

-
-##### *str: `String`*
-
-String to hash.
-
-##### *asciiOnly: `Boolean` (default: `false`)*
-
-Specify the string encoding is ASCII.
-
-#### sha224(str, asciiOnly)
-
-Hash string to sha224, set asciiOnly to true for better performace if you ensure input is ascii.
-
-##### *str: `String`*
-
-String to hash.
-
-##### *asciiOnly: `Boolean` (default: `false`)*

-## Extensions
-### jQuery
-If you prefer jQuery style, you can add following code to add a jQuery extension.
-
-Code
-```JavaScript
-jQuery.sha256 = sha256
-jQuery.sha224 = sha224
-```
-And then you could use like this:
-```JavaScript
-$.sha256('message');
-$.sha224('message');
-```
-### Prototype
-If you prefer prototype style, you can add following code to add a prototype extension.
-
-Code
-```JavaScript
-String.prototype.sha256 = function() {
-  return sha256(this);
-};
-String.prototype.sha224 = function() {
-  return sha224(this);
-};
-```
-And then you could use like this:
-```JavaScript
-'message'.sha256();
-'message'.sha224();
-```
