For the VIM settings I'm using have a look at the .vimrc file in the course material.

There are tons of VIM tutorials out there. I can especially recommend this one: https://danielmiessler.com/study/vim/ with two small difference, that instead of using 'jk' as Escape, I've remapped Escape to the Caps Lock key on an operating system level, as we will see later in this course, and I'm using the Spacebar instead of '\' for the leader key.
