Xbox One Twitch video explains it all

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.
