Clone the repo onto your local machine.
$ git clone git@github.com:maxluzuriaga/dotfiles.git ~/dotfiles
Then run the install script from within the directory to set up the symlinks in ~. The script automatically archives existing dotfiles that it replaces by moving them into the dotfiles folder with the extension .old. Useful if you want to keep the old dotfiles around for later.
$ cd ~/dotfiles
$ ./install.sh
Note that you can override or add additional configuration on local machines for Bash and Vim by creating and editing ~/.bashrc_local or ~/.vimrc_local respectively.
Inspiration / code for the install script came from jeffaco's dotfile repo.
Credit also to anishathalye for the idea of having a local vimrc file for each installation for machine-specific Vim config. Taken from his .vimrc here.
