title: How do I post a "release" on github?
body: <p>I have a few open source projects that I manage. I've been posting the <code>.tar.gz</code> releases for them to a directory on a webserver I run. I would like to post them to github. Is there a simple way to post the release and a signature for the release? My users aren't sophisticated enough to download the release with git; they want to download and install a <code>.tar.gz</code> file. Some of them may even want to verify the signature.</p>
