These were transcribed from a recent leak video which panned over every perk. (https://vid.me/Qqh2 If it's still up, its a pretty safe watch. Shows general out of context gameplay with some building exploration, combat, and inventory stuff. Pretty much a slice of what you'll be doing during any given 5 mins of the game. Not too spoilery.)
A note on this, however: this does not contain information on what every rank of every perk does. As well, some of these are descriptions for perks which the leaker had already invested points into, and thus some of the descriptions may be for 2 or 3 ranks deep into the perk and a little misleading.
Enjoy!
