+## Try it locally
+
+If the repo is a Nix flake and the PR branch contains a buildable output (package, NixOS config, etc.), include a "Try it locally" section at the end of the body. Use the GitHub owner/repo and branch name to construct the command:
+
+```
+### Try it locally
+`nix run github:<owner>/<repo>/<branch>`
+```
+
+Adjust the command as needed — `nix build` for non-runnable outputs, add `#<output>` if the default package isn't the relevant one. Omit this section entirely if the change isn't meaningfully testable via `nix run/build` (e.g., CI-only changes, documentation, non-Nix repos).
