+# Development Environment
+
+## Prerequisites
+
+- Docker Engine 24+ & Docker Compose v2
+- Node.js 22 LTS (for running app services locally)
+
+## Quick Start
+
+```bash
+# 1. Copy environment variables
+cp .env.example .env
+
+# 2. Start all infrastructure services
+docker compose up -d
+
+# 3. Verify all services are healthy
+docker compose ps
+```
+
+## Services
+
+| Service    | Port(s)      | Description                    | Dashboard/UI                    |
+| ---------- | ------------ | ------------------------------ | ------------------------------- |
+| PostgreSQL | 5432         | Database with PostGIS          | —                               |
+| Redis      | 6379         | Cache, sessions, queue         | —                               |
+| Typesense  | 8108         | Full-text search engine        | http://localhost:8108/health    |
+| MinIO      | 9000 / 9001  | S3-compatible object storage   | http://localhost:9001 (console) |
+
+## Common Commands
+
+```bash
+# Start services
+docker compose up -d
+
+# View logs (all or specific service)
+docker compose logs -f
+docker compose logs -f postgres
+
+# Stop services (data preserved in volumes)
+docker compose down
+
+# Stop and remove all data
+docker compose down -v
+
+# Restart a single service
+docker compose restart redis
+
+# Check service health
+docker compose ps
+```
+
+## Connecting to Services
+
+### PostgreSQL
+
+```bash
+# Via psql
+psql postgresql://goodgo:goodgo_secret@localhost:5432/goodgo
+
+# Verify PostGIS
+psql postgresql://goodgo:goodgo_secret@localhost:5432/goodgo -c "SELECT PostGIS_Version();"
+```
+
+### Redis
+
+```bash
+redis-cli -p 6379 ping
+```
+
+### Typesense
+
+```bash
+curl http://localhost:8108/health
+```
+
+### MinIO
+
+- API: `http://localhost:9000`
+- Console: `http://localhost:9001` (login: minioadmin / minioadmin_secret)
+
+## Troubleshooting
+
+- **Port conflict**: Change ports in `.env` (e.g., `DB_PORT=5433`)
+- **Permission issues**: Run `docker compose down -v` and restart
+- **PostGIS not available**: Ensure using `postgis/postgis:16-3.4` image
