+## Usage
+
+```js
+var pbkdf2 = require('pbkdf2')
+var derivedKey = pbkdf2.pbkdf2Sync('password', 'salt', 1, 32, 'sha512')
+
+...
+```
+
+For more information on the API, please see the relevant [Node documentation](https://nodejs.org/api/crypto.html#crypto_crypto_pbkdf2_password_salt_iterations_keylen_digest_callback).
+
+For high performance, use the `async` variant (`pbkdf2.pbkdf2`), not `pbkdf2.pbkdf2Sync`; this variant has the oppurtunity to use `window.crypto.subtle` when browserified.
+
