You are talking about kernel versions?

Version 4.12 was from July 2017 until September 2017 (0)

Right now the main line kernel is at 4.14, but it has not changed so much that it really matters for learning Linux.

I am. Do you think the same steps will work with 4.14? (Or at least that any changes I need to make would be straightforward enough for a relative beginner to figure out?)

It is impossible for me to determine your level, I would expect it to be straightforward enough.

But probably best to stick with the kernel that the doc is written for.
