How to root an Xperia ZR C5502 (FOR NOOBS) topic

Hello there fellow XDA mates.
I have been using an Xperia ZR device for some times now and I have grown bored out of the stock Xperia ROM. And I would like to root the device and install CyanogenMod or CrDroid (LOLLIPOP PREFERRED) (a classmate recommended it. He has it on his Galaxy Note 2 (android 5.0))
And so, since I am a noob at this rooting and stuff guiding me thru this step by step would be a great help.

Some basic info about my device and the android OS.
