I manage nvim-config using (GNU Stow).
Install nvim-config by cloning the git repository. I recommand using ghq.
ghq get https://github.com/helmecke/nvim-config.git
# or
git clone https://github.com/helmecke/nvim-config.git ~/.nvim-config
You can now symlink any configurations you wish to use:
# Enter repository folder
cd $(ghq list -p | grep helmecke/nvim-config)
#or
cd ~/.nvim-config
# Symlink nvim config
stow -t ~ nvim
# Remove nvim symlink
stow -t ~ -D nvim
