+
+<hr>
+
+### Sign
+#### `jwt.sign(payload, secret, [options])`
+
+Signs a payload and returns the token.
+
+#### Arguments
+
+Argument    | Type     | Satus    | Default | Description
+----------- | -------- | -------- | ------- | -----------
+`payload`   | `object` | required | -       | The payload object. To use `nbf` (Not Before) and/or `exp` (Expiration Time) add `nbf` and/or `exp` to the payload.
+`secret`    | `string` | required | -       | A string which is used to sign the payload.
+`options`   | `object` | optional | `{ algorithm: 'HS256' }` | The options object supporting `algorithm` and `keyid`. (See [Available Algorithms](#available-algorithms))
+
+#### `return`
+Returns token as a `string`.
+
+<hr>
+
+### Verify
+#### `jwt.verify(token, secret, [options])`
+
+Verifies the integrity of the token and returns a boolean value.
+
+Argument    | Type     | Satus    | Default | Description
+----------- | -------- | -------- | ------- | -----------
+`token`     | `string` | required | -       | The token string generated by `jwt.sign()`.
+`secret`    | `string` | required | -       | The string which was used to sign the payload.
+`options`   | `object` | optional | `{ algorithm: 'HS256', throwError: false }` | The options object supporting `algorithm` and `throwError`. (See [Available Algorithms](#available-algorithms))
+
+#### `throws`
+If `options.throwError` is `true` and the token is invalid, an error will be thrown.
+
+#### `return`
+Returns `true` if signature, `nbf` (if set) and `exp` (if set) are valid, otherwise returns `false`. 
+
+<hr>
+
+### Decode
+#### `jwt.decode(token)`
+
+Returns the payload **without** verifying the integrity of the token. Please use `jwt.verify()` first to keep your application secure!
+
+Argument    | Type     | Satus    | Default | Description
+----------- | -------- | -------- | ------- | -----------
+`token`     | `string` | required | -       | The token string generated by `jwt.sign()`.
+
+#### `return`
+Returns an `object` containing `header` and `payload`:
+```javascript
+{
+    header: {
+        alg: 'HS256',
+        typ: 'JWT'
+    },
+    payload: {
+        name: 'John Doe',
+        email: 'john.doe@gmail.com'
+    }
+}
+```
