[Q] Root Sony Xperia Z Tablet - Android 4.3 topic

Hi all,
I have Sony Xperia Z Tablet which I want to gain root access for.

Device details:
Model number: SGP311
16GB
Android 4.3
Build Number: 10.4.B.0.577
Not sure if relevant, but the tablet was bought in USA.

I'm pretty much a newbe here, so I would like, if possible, to get a link for a simple tutorial how to root my device.

10'x! :)
