There is a lot of frameworks dedicated for dotfile management yet they all feel overly complicated for simple thing which is symlinking files from point A to point B. For this purpose I've decided to use GNU Stow as hassle-free tool.
touch mynewdotfile
git add mynewdotfile
git commit -m "mynewdotfile"
cd ~
ls -s .dotfiles/mynewdotfile .mydotfile
