You can right click at corpse and then use knife to prepare them. Craft is in the right-down corner hammer and screwdriver. Talents in left-down corner 💡. Some bleeding you can stop with rope, some with clothe.
But really you could found it yourself, there nothing hard. I play this game 2 time and on third I walk in like at home. So just play and have fun
