This was originally included in my personal Neovim setup, but I didn't like having all the snippets there so I decided to have them separately. This is quite convenient since I can install them like any other plugin now.
The best way to install this is with your favorite plugin manager for Vim, such as vim-plug:
Plug 'UltiRequiem/vim-snippets'
