+
+This module provides native bindings to [Blake][1] [[pdf][2]]. In browser pure JavaScript implementation will be used.
+
+## Usage
+
+You can use this package as [node Hash][3].
+
+```js
+const createBlakeHash = require('blake-hash')
+
+console.log(createBlakeHash('blake256').digest().toString('hex'))
+// => 716f6e863f744b9ac22c97ec7b76ea5f5908bc5b2f67c61510bfc4751384ea7a
+
+console.log(createBlakeHash('blake256').update('Hello world!').digest('hex'))
+// => e0d8a3b73d07feca605c2376f5e54820cf8280af4a195d125ff5eadbf214adf3
