When learning something new, do you prefer a walkthough, or instructions?
For example, if you were wanting to learn Vim, would you prefer something like this (walkthrough):
Using Vim is fun. It can be hard to learn but it is worth the effort!
Move your cursor to the beginning of the 'h' in hard (using the hjkl keys) and press '4de' (to delete 4 words) and then type 'ifun and [escape]'.
or just simple instructions (imagine a better written version of this):
You can use delete to the end of a word with 'de'
You can put a number in front of a command to delete more than 1 word (example '4de')
etc... (again, imagine this is written a bit better, but hopefully you get the point).
