-# CONTRIBUTING
+# Contributing to react-simplikit
+
+Welcome! We appreciate your interest in contributing to react-simplikit. This document provides an overview of how to contribute. For detailed guidelines, please refer to the package-specific contributing guides linked below.
+
+## Contributing Guide
+
+Each contribution requires:
+
+- **Implementation** — following our [Design Principles](https://react-simplikit.slash.page/core/design-principles.html)
+- **Test Code** — 100% coverage required
+- **JSDoc** — documentation is auto-generated from JSDoc, so no separate docs needed
+
+For detailed instructions, see the package-specific guides:
+
+- [Core Package Contributing Guide](../docs/core/contributing.md)
+- [Mobile Package Contributing Guide](../docs/mobile/contributing.md)
+
+## Scaffolding
+
+Use the scaffold command to create a basic structure for new implementations:
+
+```bash
+yarn run scaffold <name> --type <type>
+```
+
+- `type`: `component`, `hook`, or `util` (shortcuts: `c`, `h`, `u`)
+- `name`: Name of the implementation
+
+## Creating a Changeset
+
+When your changes affect a package, create a changeset:
+
+```bash
+yarn changeset
+```
+
+Select the version bump type (`patch`, `minor`, or `major`).
+
+> **Note:** Both packages are currently in the `0.0.x` stage. During this phase, most changes should use `patch`. If you're unsure about the version type, please discuss with the maintainers.
