I use GNU Stow (http://brandon.invergo.net/news/2012-05-26-using-gnu-stow-to-manage-your-dotfiles.html) to manage these. If you want to start using any of my configurations:
1. install stow:
Ubuntu/Debian: sudo apt install stow
Arch: sudo pacman -S stow
2. clone the repo:
git clone git@github.com:v01dv/.dotfiles ~/.dotfiles
cd ~/.dotfiles
3. install the desired configuration files:
stow nvim
stow tmux
etc.
