Quick Start (5 minutes)

# 1. Set up database
createdb madbase_control_plane
psql madbase_control_plane < control-plane-api/migrations/001_initial.sql

# 2. Set environment variables
export DATABASE_URL="postgresql://user:pass@localhost/madbase_control_plane"
export HETZNER_API_KEY="your_hetzner_api_token"

# 3. Run Control Plane API
cd control-plane-api
cargo run --release

# 4. Add your first server
curl -X POST http://localhost:8001/api/v1/servers \
  -H "Content-Type: application/json" \
  -d '{
    "name": "worker-1",
    "template": "worker-node",
    "provider": "hetzner",
    "plan": "cx11",
    "region": "fsn1"
  }'
``
