+```
+
+## Step 2: Clone and Configure
+
+```bash
+# Clone repository
+git clone https://github.com/goa-gel/tlas.git
+cd tlas
+
+# Copy environment template
+cp .env.example .env
+```
+
+Edit `.env` with required values:
+
+```bash
+# Database
+DB_HOST=postgres
+DB_PORT=5432
+DB_USER=tlas
+DB_PASSWORD=<secure-password>
+DB_NAME=tlas
+
+# JWT
+JWT_SECRET=<64-character-random-string>
+
+# Blockchain
+BESU_RPC_URL=http://besu:8545
+CONTRACT_ADDRESS=<deployed-contract-address>
+
+# External Services
+DIGILOCKER_CLIENT_ID=<your-client-id>
+DIGILOCKER_CLIENT_SECRET=<your-secret>
+```
+
+## Step 3: Initialize Database
+
+```bash
+# Start database only
+docker-compose up -d postgres
+
+# Run migrations
+docker-compose exec api npm run migration:run
+
+# Seed initial data
+docker-compose exec api npm run seed
+```
+
+## Step 4: Deploy Blockchain
+
+```bash
+# Start Besu node
+docker-compose up -d besu
+
+# Wait for node sync
+docker-compose logs -f besu
+
+# Deploy smart contract
+docker-compose exec api npm run deploy:contract
+```
+
+## Step 5: Start Application
+
+```bash
+# Start all services
+docker-compose up -d
+
+# Verify health
+docker-compose ps
+curl http://localhost:3000/api/health
+```
+
+## Step 6: Configure SSL
+
+```bash
+# Using Certbot with Nginx
+sudo certbot --nginx -d your-domain.gov.in
+```
+
+## Verification Checklist
+
+- [ ] All containers running (`docker-compose ps`)
+- [ ] API health check returns 200
+- [ ] Frontend loads in browser
+- [ ] Database connections working
