+## Nix stuff
+
+- After entering the shell with `nix develop`, hugo is available and `hugo serve` should work
+- Python including required packages will be available, so the `build.sh` should work without a venv
+- You can build the staging and production builds with `nix build .#staging-content` and `nix build .#production-content`
+- Do not update the nixpkgs branch - 25.05 contains a newer hugo version that is incompatible with the theme (last checked June 2025)
