Here's how I would do it, very opinionatedly.

- Step 1. Use only Linux. You avoid having to translate between operating systems, you avoid paying expensive licenses, and you make your environments repeatable across dev machines. If a dev needs software that's only available on Windows or MacOS, have them run it in Docker or in a VM.

- Step 2. Define your software, programs, and user configuration in a .nix file. Create variables for user-specific stuff (usernames, email addresses, preferred software, etc.) and put them at the top of the file, so that you or the dev can easily edit it. Keep the Nix file in a Git repo, but allow your dev to maintain a separate branch. Build the Nix file into the system with `nixos-rebuild`.

- Step 3. There is no step 3.
