First thing you need to do is unlock the workbench in the survival tree, build a room/house around it so the workbench functions.
Now with the workbench you can craft a Researtch table, place it down also in a apropriate room so it functions with the researtch table you can unlock new skills, every scroll you can craft there unlocks new skills. The requirment to craft these scrolls is that you Invest points in the Researtch skill tree, to the type of scroll you want to craft.

Not a native english, so my gramer is a bit bad.
