+# Contributing
+
+## Scope
+
+This repository currently focuses on a C++20 publisher pipeline for OpenMOQ:
+
+- fragmented MP4 ingest
+- CMSF-oriented object planning
+- draft-14 primary MOQT behavior
+- draft-16 secondary compatibility mapping
+
+Transport integration is intentionally separated from packaging. Contributions should preserve that boundary unless the change explicitly introduces a transport layer.
+
+## Development
+
+```bash
+cmake -S . -B build
+cmake --build build
+ctest --test-dir build --output-on-failure
+```
+
+## Contribution Guidelines
+
+- Keep changes C++20-compatible on Linux and macOS.
+- Prefer incremental changes with tests for parser, segmenter, or packaging behavior.
+- Avoid unnecessary media copies in the MP4 to CMSF path.
+- Document draft-specific MOQT behavior in [`docs/protocol-mapping.md`](/media/mondain/terrorbyte/workspace/github/moqxr/docs/protocol-mapping.md) when protocol assumptions change.
+- If a feature depends on unstable draft behavior, isolate it behind a clearly named abstraction.
+
+## Pull Requests
+
+- Explain the user-visible or interoperability impact.
+- Note whether the change affects draft-14, draft-16, or both.
+- Include a minimal reproduction or test case when fixing parser or packaging bugs.
+
