Help a noobie please

Hello. Thanks for taking the time to look at this post.

I have been reading up on how to root my S6 Edge UK model SM-G925F. I must admit I have read to much on this I am completely lost and just need a pointer to a safe way to do so. I am a newish android user coming from iPhone and being used to jailbreak only.

I am concerned reading the issues with triggering knox and basically anything which is going to invalidate the warranty on my 3 day old S6 Edge.

Could anyone point me in the right direction and I really am sorry due to understanding this ha's been discussed in many threads.

Much appreciated. Mike.

Helllo, and greatings to all...
new to all this.
have installed cyanogenmod nightly rom on z1 and it is rooted too. but when i was doing initial backup in CWM it backed up to internal storage first, i then backed it up to sd card.
However, what if anything should i keep in the internal storage?
i may have put stuff in ther and want a nice clean machine.
am presently doing titanium backup, but also find that i couldn't change the backup location to the sd card either!!
any help would be greatly appreciated.
Leo

p.s.
you may have to walk me through doing a directory list of internals.
