+# Contributing to ReactiveMP
+
+**ReactiveMP.jl** is a community-driven reactive message passing engine and we welcome contributions of all kinds!
+
+ReactiveMP is part of the [ReactiveBayes](https://github.com/ReactiveBayes) organization and the broader [RxInfer](https://github.com/ReactiveBayes/RxInfer.jl) ecosystem for reactive Bayesian inference in Julia.
+
+## Getting Started
+
+* Browse **beginner-friendly issues**: https://github.com/ReactiveBayes/ReactiveMP.jl/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22
+* Check out the [RxInfer Contributing Guide](https://docs.rxinfer.com/stable/contributing/guide) for general conventions shared across the ecosystem
+
+We welcome contributions such as:
+
+* Bug reports and fixes
+* New message passing rules and nodes
+* Documentation improvements
+* Tests and performance improvements
+* Feature suggestions
+
+## Development Workflow
+
+1. Fork the repository and create a feature branch
+2. Make your changes and ensure tests pass locally with `make test`
+3. Run `make format` to ensure consistent code formatting
+4. Open a pull request against `main` — the CI will check tests, formatting, and that `CHANGELOG.md` has been updated
+
+## Contributing to the RxInfer Ecosystem
+
+ReactiveMP is one of several packages in the RxInfer ecosystem. Contributions to any of these projects are very welcome:
+
+- [RxInfer.jl](https://github.com/ReactiveBayes/RxInfer.jl) — the high-level inference package
+- [GraphPPL.jl](https://github.com/ReactiveBayes/GraphPPL.jl) — probabilistic model specification
+- [ExponentialFamily.jl](https://github.com/ReactiveBayes/ExponentialFamily.jl) — exponential family distributions
+- Browse other packages at https://github.com/ReactiveBayes
