+Referrer Policy
+===============
+[![Build Status](https://travis-ci.org/helmetjs/referrer-policy.svg?branch=master)](https://travis-ci.org/helmetjs/referrer-policy)
+
+The [Referer HTTP header](https://en.wikipedia.org/wiki/HTTP_referer) is typically set by web browsers to tell the server where it's coming from. For example, if you click a link on *example.com/index.html* that takes you to *wikipedia.org*, Wikipedia's servers will see `Referer: example.com`. This can have privacy implications—websites can see where you are coming from. The new [`Referrer-Policy` HTTP header](https://www.w3.org/TR/referrer-policy/#referrer-policy-header) lets authors control how browsers set the Referer header.
+
+[Read the spec](https://www.w3.org/TR/referrer-policy/#referrer-policies) to see the options you can provide.
+
+Usage:
+
+```javascript
+const referrerPolicy = require('referrer-policy')
+
+app.use(referrerPolicy({ policy: 'same-origin' }))
+// Referrer-Policy: same-origin
+
+app.use(referrerPolicy({ policy: 'unsafe-url' }))
+// Referrer-Policy: unsafe-url
+
+app.use(referrerPolicy())
+// Referrer-Policy: no-referrer
+```
