+# Contributing
+
+Contributions that improve compatibility, backup safety, documentation, or Linux distribution
+support are welcome.
+
+## Before opening a pull request
+
+1. Base changes on the current default branch and keep each pull request focused.
+2. Preserve Bash 4+ compatibility and LF line endings.
+3. Do not add bundled credentials, save data, backups, or unreviewed executables.
+4. Keep the REST API loopback-only by default.
+5. Update the README and changelog when user-visible behavior changes.
+
+Run the same checks used by CI:
+
+```bash
+bash -n palworld-manager.sh
+sh -n helper.sh
+shellcheck palworld-manager.sh helper.sh
+cp .env.example .env
+docker compose config --quiet
+```
+
+For backup, restore, or update changes, describe the failure and rollback cases you tested in the
+pull-request body.
