+# Contributing to ObsidianDragon
+
+Thank you for your interest in contributing! This guide will help you get started.
+
+## Getting Started
+
+1. Fork the repository
+2. Clone your fork and create a branch:
+   ```bash
+   git clone https://git.hush.is/<your-username>/ObsidianDragon.git
+   cd ObsidianDragon
+   git checkout -b my-feature
+   ```
+3. Install dependencies:
+   ```bash
+   ./scripts/setup.sh
+   ```
+4. Build:
+   ```bash
+   ./build.sh --linux-release   # or --win-release, --mac-release
+   ```
+
+## Development Workflow
+
+### Code Style
+
+- C++17 standard
+- Use the Material Design icon font (`ICON_MD_*` defines) — never raw Unicode symbols
+- UI layout values go in `res/themes/ui.toml`, read via `schema::UI()` — never hardcode pixel sizes
+- Use the `RPCWorker` for all RPC calls — never block the main thread with synchronous curl
+
+See `.github/copilot-instructions.md` for detailed coding standards.
+
+### Building
+
+```bash
+# Linux debug build (fastest iteration)
+cd build && make -j$(nproc)
+
+# Full release builds
+./build.sh --linux-release
+./build.sh --win-release
+./build.sh --mac-release
+```
+
+### Testing
+
+Run the wallet and verify:
+- Daemon connection and sync
+- Lock screen / PIN unlock
+- Send and receive transactions
+- All tabs render correctly
+
+## Submitting Changes
+
+1. Commit with clear, descriptive messages
+2. Push to your fork
+3. Open a Pull Request against `main`
+4. Describe what changed and why
+
+### Pull Request Guidelines
+
+- Keep PRs focused — one feature or fix per PR
+- Ensure the project builds on Linux (`make -j$(nproc)`)
+- Test cross-compilation if touching platform-specific code (`./build.sh --win-release`)
+- Update `res/themes/ui.toml` if adding new UI layout values
+
+## Reporting Issues
+
+- Use the [issue tracker](https://git.hush.is/dragonx/ObsidianDragon/issues)
+- Include: OS, wallet version, steps to reproduce, expected vs actual behaviour
+- For crashes: include any terminal output
