`flakes` is a feature available in the unstable version of the `nix` package manager to ease the distribution of nix expressions see https://www.tweag.io/blog/2020-05-25-flakes/ . Nix excels at software reproducibility and is available/can be installed on different distributions (ubuntu/void/debian etc) as well as macOS. This flakes contains 3 packages that can be installed via for instance `nix run 'github:neovim/neovim?dir=contrib#nvim-debug'` or `nix run 'github:neovim/neovim?dir=contrib'` for the default version. you can register an alias `nix registry add neovim 'github:neovim/neovim?dir=contrib'` and the previous commands become: `nix run neovim`
