+
+## Requirements
+- **Go Version**: 1.26 or higher is required.
+- **Tools**: `golangci-lint` and `task` (Taskfile.dev) are recommended.
+
+## Development Workflow
+1. **Testing**: Ensure all tests pass before submitting changes.
+   ```bash
+   go test ./...
+   ```
+2. **Code Style**: All code must follow standard Go formatting.
+   ```bash
+   gofmt -w .
+   go vet ./...
+   ```
+3. **Linting**: We use `golangci-lint` to maintain code quality.
+   ```bash
+   golangci-lint run ./...
+   ```
+
+## Commit Message Format
+We follow the [Conventional Commits](https://www.conventionalcommits.org/) specification:
+- `feat`: A new feature
+- `fix`: A bug fix
+- `docs`: Documentation changes
+- `refactor`: A code change that neither fixes a bug nor adds a feature
+- `chore`: Changes to the build process or auxiliary tools and libraries
+
+Example: `feat: add new ethics probe for sovereignty`

 # LEM — Lethean Ethics Model
 
 A 1-billion-parameter model trained with 5 axioms consistently outperforms untrained models 27 times its size. The axioms resist being removed. This wasn't designed — it emerged from the mathematics.
