vim Differences between Neovim and Vim Configuration Files
Example
In Vim, your configuration file is ~/.vimrc, with further configuration files in ~/.vim.
In Neovim, configuration files are located in ~/.config/nvim. There is also no ~/.nvimrc file. Instead, use ~/.config/nvim/init.vim.
You can import your Vim configuration directly into Neovim using this Unix command:
ln -s ~/.vimrc ~/.config/nvim/init.vim
