+# Contributing to arcline-uptime
+
+This project is maintained by one person. Contributions are welcome — please read this first.
+
+## Reporting bugs
+
+Open an issue with:
+- What you did
+- What you expected
+- What happened instead
+- OS, Go version, and any relevant config
+
+## Suggesting features
+
+Open an issue before writing code. A quick discussion saves everyone time — not every feature fits the scope of this tool.
+
+## Submitting a pull request
+
+1. Fork the repo and create a branch from `main`
+2. Keep changes focused — one fix or feature per PR
+3. If adding a feature, update the README to reflect it
+4. Make sure it compiles and existing behavior still works
+5. Open the PR with a clear description of what it does and why
+
+## Code style
+
+- Standard Go formatting (`gofmt`)
+- No external dependencies without a good reason
+- Prefer clear over clever
+
+## What gets merged
+
+This is a small project with a specific scope. PRs that fix real bugs or add clearly useful features will be merged. PRs that add complexity without clear benefit probably won't — no hard feelings.
+
+## License
+
+By submitting a pull request, you agree that your contribution will be licensed under the same license as this project.
