## Prerequisites

- Docker 24+ and Docker Compose 2.20+
- Git 2.x

## Installation

```bash
# Clone repository
git clone https://git.mosaicstack.dev/mosaic/stack mosaic-stack
cd mosaic-stack

# Copy environment file
cp .env.example .env

# Start all services
docker compose up -d

# Run migrations
docker compose exec api pnpm prisma migrate deploy

# Seed development data (optional)
docker compose exec api pnpm prisma:seed
```

## Verify Installation

```bash
# Check API health
curl http://localhost:3001/health

# Expected response:
# {"status":"ok","timestamp":"...","uptime":...}

# View logs
docker compose logs -f api
```

## What's Running?

| Service | Port | Purpose |
|---------|------|---------|
| API | 3001 | NestJS backend |
| PostgreSQL | 5432 | Database |
| Valkey | 6379 | Cache (Redis-compatible) |

## Next Steps

1. **Configure Authentication** — See [Configuration → Authentik](../3-configuration/2-authentik.md)
2. **Explore the API** — Check [API Reference](../../4-api/README.md)
3. **Start Developing** — Read [Development → Workflow](../../2-development/1-workflow/1-branching.md)

## Troubleshooting

**Port already in use:**
```bash
# Stop existing services
docker compose down

# Check what's using the port
lsof -i :3001
```

**Database connection failed:**
```bash
# Check PostgreSQL is running
docker compose ps postgres

# View PostgreSQL logs
docker compose logs postgres
```
