 A simple SHA-3 / Keccak / Shake hash function for JavaScript supports UTF-8 encoding.
 
 ## Notice
-Sha3 methods has been renamed to keccak since v0.2.0. It means that sha3 methods of v0.1.x are equal to keccak methods of v0.2.x and later.
+* Sha3 methods has been renamed to keccak since v0.2.0. It means that sha3 methods of v0.1.x are equal to keccak methods of v0.2.x and later.

-### jQuery
-If you prefer jQuery style, you can add following code to add a jQuery extension.
-
-Code
-```JavaScript
-jQuery.sha3_512 = sha3_512;
-jQuery.sha3_384 = sha3_384;
-jQuery.sha3_256 = sha3_256;
-jQuery.sha3_224 = sha3_224;

-jQuery.keccak_384 = keccak_384;
-jQuery.keccak_256 = keccak_256;
-jQuery.keccak_224 = keccak_224;
-```
-And then you could use like this:
-```JavaScript
-$.sha3_512('message');
-$.sha3_384('message');
-$.sha3_256('message');
-$.sha3_224('message');
-$.keccak_512('message');
-$.keccak_384('message');
-$.keccak_256('message');
-$.keccak_224('message');
-```
-### Prototype
-If you prefer prototype style, you can add following code to add a prototype extension.
-
-Code
-```JavaScript
-String.prototype.sha3_512 = function() {
-  return sha3_512(this);
-};
-String.prototype.sha3_384 = function() {
-  return sha3_384(this);
-};
-String.prototype.sha3_256 = function() {
-  return sha3_256(this);
-};
-String.prototype.sha3_224 = function() {
-  return sha3_224(this);

-  return keccak_256(this);
-};
-String.prototype.keccak_224 = function() {
-  return keccak_224(this);
-};
-```
-And then you could use like this:
-```JavaScript
-'message'.sha3_512();
-'message'.sha3_384();
-'message'.sha3_256();
-'message'.sha3_224();
-'message'.keccak_512();
