I find people often rely too much on guides which just tell you the steps, and you never learn how it actually works. So I would emphasize the manual bit to understand what that thing the guide told you to do actually does.
The other big hurdle is not being able to assess information for accuracy. If you have no prior knowledge, you have no clue whether that blog post with a guide you found is written by someone clueless or a genius. I've had that problem before on a topic I was unfamiliar with, and literally had to just ask an experienced person whether this looked okay or not. They were happy to correct all the misinformation I almost followed.
On a related note, it's always easier to make people give corrections than tell you everything from scratch. Just human nature.
