+   cd auth0-deploy-cli
+   ```
+3. **Add upstream** remote:
+   ```bash
+   git remote add upstream https://github.com/auth0/auth0-deploy-cli.git
+   ```
+
+### Development Setup
+
+```bash
+# Install dependencies
+npm ci
+```
+
+## Development Workflow
+
+### Create Feature Branch
+
+```bash
+# Sync with upstream
+git fetch upstream
+git checkout master
+git merge upstream/master
+
+# Create feature branch
+git checkout -b feature/your-feature-name
+```
+
+### Development Commands
+
+```bash
+# Development with watch mode
+npm run dev
+
+# Run tests
+npm test
+
+# Run single test file
+npx ts-mocha test/path/to/specific.test.ts
+
+# Lint and format
+npm run lint:fix
+npm run format
+
+# Check TypeScript compilation
+npx tsc --noEmit
+
+# Run CLI locally for testing
+npm run build && node lib/index.js --help
+```
+
+### Testing Requirements
+
+Before submitting a PR, ensure all tests pass:
+
+```bash
+# Unit tests (required)
+npm test
+```
+
+### Testing Your Changes Locally
+
+To test your changes with the actual CLI:
+
+```bash
+# Build the project
+npm run build
+
+# Run CLI commands locally
+node lib/index.js --help
+node lib/index.js export --help
+node lib/index.js import --help
+
+# Example: Test export command
+node lib/index.js export -c config.json -f yaml -o ./local-export/

+# Example: Test import command
+node lib/index.js import -c config.json -i ./local-export/tenant.yaml
+```
+
+### Running Individual Tests
