Don't put any lines in your vimrc that you don't understand.
I would agree with that statement — for intermediate and advanced users. If you're new to the shell, starting with a framework or someone else's dotfiles bootstrap can ease your immersion into text mode.
Your goal should be to get comfortable enough to craft your own workflow and build your .vimrc from the ground up.
