You can install dotfiles by cloning the repository as .dotfiles in your home directory and running the bootstrap script.
$ git clone git@github.com:50bhan/dotfiles.git .dotfiles
$ cd .dotfiles
$ ./bootstrap.sh
As an alternative, you can download downloader.sh script and just run it. It will clone the repository in your home directory, and then run bootstrap script for you.
$ ./downloader.sh
