Basic Mods Questions- Unlock, Root, AdAway, Tether, TWRP

When I get phone I'm most interested in doing build prop edit for tether, installing custom recovery TWRP for 6P and AdAway would be nice. Loss of Google Pay not a show stopper. Would like to do OTA factory image updates or modified images until custom ROMs and Kernels mature.
Can someone please post idiot proof specific instructions or guide links. I know some basics but assume others do not.
Thanks

Hotspot tether WITHOUT root

Hello,

For those of us waiting for a root option on 5.1.1, I found a great app that works as hotspot for free.

FoxFi on playstore. Has a paid version as well.

Thought I'd share.
