Hi.
If you look in the box the Surface studio arrived in there is a small quick start.
For the more in depth stuff open the windows start and click the shortcut icon that says 'SURFACE'. You will find more basic functionality of the device there, click 'get started' for the quick tour.
There is a link to the Tips App, which will lay out the more advanced and integration concepts for the surface studio.
The rest you'll have to find yourself as you walk that road of discovery, pro-tip 'if in doubt' "Google is your friend".
