+## Contributing
+
+When adding new features or fixes, update this file with:
+1. Issue number (from GitHub)
+2. Concise description of the change
+3. Any cross-references to related issues
+4. Placement in the appropriate category section
+
+Every merged PR that touches contract logic or introduces new features should include a CHANGELOG entry.
+
+## Version Release Schedule
+
+Release tags follow semantic versioning (`v1.0.0`, `v1.1.0`, etc.) and are created based on feature readiness, not calendar-based schedules. See the [GitHub Releases](https://github.com/AtomicIP/AtomicIP-/releases) page for version history.

+## 🚀 JS Batch & Analytics Layer
+
+The `src/` directory contains the JavaScript/TypeScript batch operations and SDK modules that complement the Soroban smart contracts. This layer provides:
+
+- **Batch Operations**: Efficient multi-swap processing, cancellation, and dispute resolution
+- **SDK Modules**: Type-safe interfaces for interacting with the on-chain contract
+- **Analytics**: Fee calculation, reputation scoring, and transaction analysis
+- **Testing**: Comprehensive Jest test suite covering all batch workflows
+
+### Setup and Testing
+
+Install dependencies:
+
+```bash
+npm install
+```
+
+Run the full JS test suite:
+
+```bash
+npm test
+```
+
+Run tests with coverage report:
+
+```bash
+npm run test:coverage
+```
+
+Run tests in watch mode (useful during development):
+
+```bash
+npm run test:watch
+```
+
+The test suite covers:
+- Batch swap cancellation logic
+- Dispute resolution workflows
+- Fee calculation and escrow handling
+- Multi-currency support
+- SDK module integration
