Twitch streaming will finally launch on Xbox One next Tuesday, with the launch of an update which makes the Twitch app actually useful. Microsoft has whipped together a video demonstrating exactly how it'll all work, from setting up your own stream to watching your chums. You know: streaming.

Microsoft's Larry 'Major Nelson' Hryb also explains a few steps you can take now to prepare for Twitch streaming, so you can leap straight into it once the update goes live. You'll want to sign up for a Twitch account, and fiddle with your system settings to make sure it'll all work.
