   So, here's how to go about making it work:
   
  -. Download the version of `apln-boot` http://www.eclipse.org/jetty/documentation/9.4.x/alpn-chapter.html#alpn-versions[corresponding to your version of Java]. The binaries are available on https://repo1.maven.org/maven2/org/mortbay/jetty/alpn/alpn-boot/[Maven Central], or you can build your own if you prefer.
  +. Download the version of `apln-boot` {url-alpn-boot-list}[corresponding to your version of Java]. The binaries are available on {url-alpn-boot-bin}[Maven Central], or you can build your own if you prefer.
   
   . When launching your verticle, put `alpn-boot` on the JVM's _boot classpath_; it's altering core library functionality and needs to be available early. There are a few ways to do this, here's the easiest one:

  ```
  
  You'll likely want to check that it's really working. I've been using `cURL` compiled with `nghttp2` to enable HTTP/2 support, depending on your OS or distro, the built-in version it may already be there. If you're using OS X, you can do `brew install curl --with-nghttp2` footnote:[But remember cURL not linked by default so you'll have to dig into its Cellar (e.g. /Cellar/curl/7.50.1/bin/curl). Of course, you could alias it, or force link :-)]
  
  ```shellsession
   $  curl -k -v --http2 https://localhost:8443/
