Go to the repo directory and run:
sh install.sh
Your old vim setup (if you had one) will be named .vimrc_backup and .vim_backup.
I advise to look at the installation script before running it.
Later on, I plan on putting user's old vim set up in a different folder. Along with a restoration script.
Plugins used:
