In order to use this, you simply need to copy paste the skills into you skill queue.
To do this, open your character sheet, go to skills, and on the bottom where your skill queue is listed, the top left of that interface has a button marked with four horizontal lines. Click that, and press 'replace skills with clipboard'.
Bear in mind that you can only have a max of 50 skills in your queue at a time, so you will have to copy paste this list a few times to complete it. The game will also recognize skills you already have, and filter them out, so simply copy paste the text from the file until nothing shows up!
If you need a skillbook package, please contact That Randomguy Uitoh in game.
