+# Agent Commerce Kit (ACK)
+
+## Project Overview
+
+**Agent Commerce Kit (ACK)** is an open-source TypeScript framework enabling AI agents to participate in commerce through two core protocols:
+
+1. **ACK-ID**: Verifiable AI identities with compliance controls using W3C DIDs and Verifiable Credentials
+2. **ACK-Pay**: Secure, automated payment processing with auditable receipt verification
+
+The project is structured as a **pnpm monorepo** with Turbo build orchestration, requiring Node.js 22+ and pnpm 10+.
+
+## Essential Commands
+
+### Setup & Development
+
+```bash
+pnpm run setup          # Initialize repository (install deps, build packages)
+pnpm run build          # Build all packages
+pnpm run dev:examples   # Run all example services
+pnpm run dev:docs       # Run documentation site locally
+```
+
+### Quality Assurance
+
+```bash
+pnpm run check          # Run comprehensive checks (format, types, lint, test)
+pnpm run test           # Run all tests
+pnpm run lint           # Run ESLint
+pnpm run check:types    # TypeScript type checking
+pnpm run format         # Format code with Prettier
+```
+
+### Demos
+
+```bash
+pnpm demo:identity      # ACK-ID protocol demonstration
+pnpm demo:identity-a2a  # ACK-ID with Google A2A protocol
+pnpm demo:payments      # ACK-Pay protocol demonstration
+pnpm demo:e2e           # End-to-end demo (ACK-ID + ACK-Pay)
+pnpm demo:skyfire-kya   # Skyfire KYA token demonstration
+```
+
+### Testing
+
+- Run individual package tests: `pnpm --filter ./packages/[package-name] test`
+- All tests use **Vitest** framework with assertive testing patterns (`it('requires...')`, `it('throws...')`, `it('returns...')`)
+- Test configuration: individual `vitest.config.ts` files per package
+
+## Architecture
+
+### Core Packages (`/packages/` - Published to NPM)
+
+- **`agentcommercekit/`** - Main SDK package (exports everything)
+- **`ack-id/`** - Identity protocol implementation
+- **`ack-pay/`** - Payment protocol implementation
+- **`caip/`** - CAIP (Chain Agnostic Improvement Proposal) utilities for CAIP-2, CAIP-10, and CAIP-19
+- **`did/`** - Decentralized Identifier utilities
+- **`jwt/`** - JWT creation/verification utilities
+- **`keys/`** - Cryptographic key management (Ed25519, secp256k1, secp256r1)
+- **`vc/`** - Verifiable Credentials utilities
+
+### Demonstrations (`/demos/`)
+
+Interactive demos showcasing protocol functionality - each can be run independently.
+
+### Example Services (`/examples/`)
+
+Standalone service implementations including credential issuer, verifier, and local DID host.
+
+### Build System
+
+- **Turbo**: Orchestrates builds across packages with dependency graph
+- **tsdown**: TypeScript compiler/bundler
+- **Output**: `dist/` directories with ESM and TypeScript definitions
+- **Dependency Management**: Exact versions for dependencies (enforced via `.npmrc`), ranges for peer dependencies
+
+### Key Technical Patterns
+
+- **ESM-only**: All packages use `"type": "module"`
+- **Multi-curve Cryptography**: Ed25519, secp256k1, secp256r1 support
+- **Dual Validation**: Both Valibot (primary) and Zod (peer dependency) support
+- **Standards Compliance**: W3C DIDs and Verifiable Credentials
+- **Modular Design**: Protocols can be used independently
+
+### Development Workflow
+
+1. Changes to core packages require rebuilding: `pnpm run build`
+2. Use `pnpm --filter ./packages/[name]` to work on specific packages
+3. Run comprehensive checks before commits: `pnpm run check`
+4. Demos and examples depend on built packages
+
+### Key Dependencies
+
+- **@noble/curves**: Elliptic curve cryptography
+- **multiformats**: Multiformat encoding/decoding
+- **valibot**: Runtime validation (primary choice)
+- **zod**: Alternative validation (peer dependency)
