+**Protocol-level Governance for AI Reasoning & Output Authorization**
+
+The VARX (Vector Architecture for Reasoning eXecution) Protocol provides a cryptographically-verified governance framework for AI systems, enabling secure decision-making with immutable audit trails.
+
+## Overview
+
+The Lexicoding Governance Protocol implements a three-node architecture that ensures:
+
+- **Authenticity**: All messages are cryptographically signed with Ed25519
+- **Integrity**: Tamper-evident hash chains protect audit records
+- **Non-Repudiation**: Digital signatures prevent denial of actions
+- **Replay Protection**: Secure nonces prevent message replay attacks
+
+## Architecture

+### Components
+
+| Node | Purpose |
+|------|---------|
+| **ModelNode** | AI system interface - generates signed governance requests |
+| **VARXNode** | Decision engine - evaluates reasoning with π_varx semantic analysis |
+| **AuditorNode** | Audit trail - maintains cryptographic hash chain of all decisions |
+
+## Features
+
+-  **Ed25519 Digital Signatures** - 128-bit security for message authentication
+-  **SHA256 Hash Chains** - Tamper-evident audit trails
+-  **π_varx Semantic Engine** - AI reasoning pathway analysis
+-  **Configurable Rule Bundles** - Flexible governance policies
+- **HKDF Key Derivation** - Secure key management
+-  **Replay Protection** - Secure nonces prevent attacks
+
+## Installation
+
+### Requirements
+
+- Python 3.9 or higher
+- pip (Python package installer)
+
+### Install from source
+
+```bash
+# Clone the repository
+git clone https://github.com/Lexicoding-systems/Lexicoding-Governance.git
+cd Lexicoding-Governance
+
+# Install the package
+pip install -e .
+```
+
+### Install dependencies only
+
+```bash
+pip install -r requirements.txt
+```
+
+### Development installation
+
+```bash
+pip install -e ".[dev]"
+```
+
+## Quick Start
+
+```python
+from core.crypto import generate_keypair, sign_message, verify_signature
+
+# Generate node identity
+private_key, public_key = generate_keypair()
+
+# Sign a governance request
+request = {
+    "type": "governance_request",
+    "action": "data_access",
+    "reasoning": {"steps": [{"step": 1, "reasoning": "User consent obtained"}]}
+}
+signature = sign_message(request, private_key)
+
+# Verify the signature
+is_valid = verify_signature(request, signature, public_key)
+print(f"Signature valid: {is_valid}")
+```
