## 📋 Quick Start (30 minutes)

### 1. Local Development
```bash
# Start all services
docker-compose up -d

# Verify connections
redis-cli ping
nats-cli server info
psql $DATABASE_URL -c "SELECT 1"
cypher-shell -a $NEO4J_URI "RETURN 1"
curl http://localhost:7700/health
```

### 2. Go Integration
```bash
# Install packages
go get github.com/redis/go-redis/v9
go get github.com/nats-io/nats.go
go get github.com/neo4j/neo4j-go-driver/v5
go get github.com/meilisearch/meilisearch-go

# Create clients in main.go
# See INFRASTRUCTURE_INTEGRATION_COMPLETE.md
```

### 3. Environment Variables
```bash
# .env.local
REDIS_URL=redis://localhost:6379
NATS_URL=nats://localhost:4222
DATABASE_URL=postgresql://...
NEO4J_URI=neo4j://localhost:7687
NEO4J_USER=neo4j
NEO4J_PASSWORD=password
MEILISEARCH_URL=http://localhost:7700
MEILISEARCH_KEY=masterKey
```
