+tweetnacl-util-js
+=================
+
+String encoding utilities extracted from <https://github.com/dchest/tweetnacl-js>
+
+Encoding/decoding functions are provided for convenience. They are correct,
+however their performance and wide compatibility with uncommon runtimes is not
+something that is considered important compared to the simplicity and size of
+implementation. **Please use better third-party libraries if you need to.**
+
+Installation
+------------
+
+Use a package manager:
+
+[Bower](http://bower.io):
+
+    $ bower install tweetnacl-util
+
+[NPM](https://www.npmjs.org/):
+
+    $ npm install tweetnacl-util
+
+or [download source code](https://github.com/dchest/tweetnacl-util-js/releases).
+
+
+Usage
+------
+
+To make keep backward compatibility with code that used `nacl.util` previously
+included with TweetNaCl.js, just include it as usual:
+
+```
+<script src="nacl.min.js"></script>
+<script src="nacl-util.min.js"></script>
+<script>
+  // nacl.util functions are now available, e.g.:
+  // nacl.util.decodeUTF8
+</script>
+```
+
+When using CommonJS:
+
+```
+var nacl = require('tweetnacl');
+nacl.util = require('tweetnacl-util');
+```
+
+
+Documentation
+-------------
+
+#### nacl.util.decodeUTF8(string)
+
+Decodes string and returns `Uint8Array` of bytes.
+
+#### nacl.util.encodeUTF8(array)
+
+Encodes `Uint8Array` or `Array` of bytes into string.
+
+#### nacl.util.decodeBase64(string)
+
+Decodes Base-64 encoded string and returns `Uint8Array` of bytes.
+
+#### nacl.util.encodeBase64(array)
+
+Encodes `Uint8Array` or `Array` of bytes into string using Base-64 encoding.
