 - After entering the shell with `nix develop`, hugo is available and `hugo serve` and `./build.sh` should work
 - 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

+- The theme accepts a limited range of Hugo versions, declared as `[module.hugoVersion]` in
+  `themes/blowfish/config.toml`. Blowfish v2.106.0 wants 0.158.0 to 0.165.0, the nixpkgs branch pinned in `flake.nix`
+  carries 0.163.3. Keep the two in range when updating either of them, Hugo warns on every build otherwise.
