How do you uninstall Pathogen for vim?

I installed NERDTree with Pathogen, then was not successful in installing snipMate plugin. This is my 3rd day now and I'm giving up on pathogen. I'm trying vundle. Questions:

1. Do I have to uninstall pathogen? If yes, how? Step by step method please since I'm new to Mac(Osx 10.9) and coding.
2. Do I have to delete .vim/autoload directory since it's part of pathogen?

If you want to uninstall it,

• delete ~/.vim/autoload/pathogen.vim,

• delete the lines you have added to ~/.vimrc.

Also, see this guide I wrote about Pathogen.
