First install packer
git clone --depth 1 https://github.com/wbthomason/packer.nvim\
~/.local/share/nvim/site/pack/packer/start/packer.nvim
Copy all files in ~/.config
cp -R nvim ~/.config/nvim
Then inside lua/shinji/pakcer.lua do a ":so" and save. After that type ":PackerSync"; it will sync packer with the file and ainstall all plugins.
Restart nvim and voilà!
