## 🚀 Get Started in 3 Steps

### Step 1: Set Up Environment (5 minutes)
```bash
# Create virtual environment
python -m venv venv
source venv/bin/activate  # Windows: venv\Scripts\activate

# Install dependencies
pip install -r requirements-dev.txt

# Configure environment
cp .env.example .env
# Edit .env with your Supabase credentials
```

### Step 2: Start Services (2 minutes)
```bash
# Start PostgreSQL and Redis
docker-compose up -d

# Verify services
docker-compose ps
```

### Step 3: Run the Application (1 minute)
```bash
# Start development server
uvicorn src.app.main:app --reload

# Visit http://localhost:8000
# API docs at http://localhost:8000/api/docs
```

## 🎓 Development Workflow

### 1. Implement a Feature
```
Model → Schema → Repository → Service → API → Test
```

### 2. Example: Add Ticket Creation
1. **Model**: Define Ticket table in `src/app/models/ticket.py`
2. **Schema**: Define TicketCreate in `src/app/schemas/ticket.py`
3. **Repository**: Add create() in `src/app/repositories/ticket_repository.py`
4. **Service**: Add business logic in `src/app/services/ticket_service.py`
5. **API**: Add POST endpoint in `src/app/api/v1/tickets.py`
6. **Test**: Write tests in `tests/unit/services/test_ticket_service.py`

### 3. Create Database Migration
```bash
alembic revision --autogenerate -m "Add tickets table"
alembic upgrade head
```

### 4. Run Tests
```bash
pytest
pytest --cov=src/app
```

## 💡 Pro Tips

1. **Follow the Build Plan**: It's designed for logical progression
2. **Start with Models**: Get the database structure right first
3. **Test as You Go**: Write tests alongside implementation
4. **Use the Schema**: Reference `schema.sql` for exact table definitions
5. **Commit Often**: Small, focused commits are easier to review

## 🎯 Your First Task

**Implement the User Model** (Phase 1, Day 3-4)

1. Open `src/app/models/user.py`
2. Reference `docs/schema/schema.sql` (lines 1-400)
3. Implement:
   - Users table
   - UserFinancialAccounts table
   - UserAssetAssignments table
   - UserPreferences table
4. Create migration: `alembic revision --autogenerate -m "Add user tables"`
5. Apply migration: `alembic upgrade head`
6. Test: Create a user in the database
