Installation:

1. Clone the repository to your home directory:
    git clone [email protected]:frimicc/dotvim.git ~/.vim

2. Create a symlink for the default .vimrc & .gvimrc locations:
    ln -s ~/.vim/vimrc ~/.vimrc
    ln -s ~/.vim/gvimrc ~/.gvimrc

3. Load the submodules (all the bundles):
    cd ~/.vim
    git submodule update --init

That should be it! You should be ready to use vim and enjoy my dotvim options.

------
Make changes to master branch and add, commit, and push them to GitHub.
