+
+## API
+
+### resolveALPN(options)
+
+Returns an object with an `alpnProtocol` property. The `socket` property may be also present.
+
+```js
+const result = await resolveALPN({
+	host: 'nghttp2.org',
+	port: 443,
+	ALPNProtocols: ['h2', 'http/1.1'],
+	servername: 'nghttp2.org'
+});
+
+console.log(result); // {alpnProtocol: 'h2'}
+```
+
+**Note:** While the `servername` option is not required in this case, many other servers do. It's best practice to set it anyway.
+
+**Note:** If the socket times out, the promise will resolve and `result.timeout` will be set to `true`.
+
+#### options
+
+Same as [TLS options](https://nodejs.org/api/tls.html#tls_tls_connect_options_callback).
+
+##### options.resolveSocket
+
+By default, the socket gets destroyed and the promise resolves.<br>
+If you set this to true, it will return the socket in a `socket` property.
+
+```js
+const result = await resolveALPN({
+	host: 'nghttp2.org',
+	port: 443,
+	ALPNProtocols: ['h2', 'http/1.1'],
+	servername: 'nghttp2.org',
+	resolveSocket: true
+});
+
+console.log(result); // {alpnProtocol: 'h2', socket: tls.TLSSocket}
+
+// Remember to destroy the socket if you don't use it!
+result.socket.destroy();
+```
