## 🚀 Quick Start

### Step 1: Read the Overview
Start with **00-MVP-OVERVIEW.md** to understand:
- MVP scope and objectives
- Development approach (Walking Skeleton + Vertical Slices)
- Story dependencies
- Timeline estimates

### Step 2: Setup Your Environment
Follow **01-TECHNICAL-SETUP.md** to:
- Install prerequisites (Java 17+, Node.js 18+, PostgreSQL 16, Docker)
- Setup Spring Boot backend project
- Setup Angular 18 frontend project
- Configure Docker Compose for local development
- Understand project structure and conventions

### Step 3: Start Development
Begin with **Story 0** (Foundation) and follow the story sequence:

```
Story 0: Foundation (Walking Skeleton)
    ↓
Story 1: Business Units
    ↓
Story 2: Applications
    ↓
Story 3: Contacts (can be parallel with Story 4)
    ↓
Story 4: Environments (enhancement)
    ↓
Story 5: Versions
    ↓
Story 6: Deployments
    ↓
Story 7: Current State & History
```

## ✅ Success Criteria

The MVP will be considered successful when:

1. **Functional Completeness**
   - All 8 stories delivered and accepted
   - All acceptance criteria met
   - Zero critical bugs

2. **Technical Quality**
   - Backend test coverage > 80%
   - Frontend test coverage > 70%
   - All APIs documented in Swagger
   - Code passes security review

3. **User Satisfaction**
   - Users can perform core workflows without training
   - System performance < 500ms API response
   - Positive feedback from pilot users

4. **Business Value**
   - All applications registered in system
   - Deployment history accurate and complete
   - Users prefer LDPv2 over previous tools

---

## 🧪 Testing Strategy

### Backend Testing
- **Unit Tests**: Service layer with Mockito (>80% coverage)
- **Integration Tests**: Controllers with Testcontainers
- **API Tests**: REST Assured or MockMvc

### Frontend Testing
- **Unit Tests**: Components and services (>70% coverage)

   - Implement Angular service
   - Create components (list, detail, form)
   - Add routing
   - Write tests (unit + E2E)
5. **Review**: Code review, test review
6. **Demo**: Demonstrate to stakeholders
7. **Merge**: Merge to main branch
8. **Document**: Update API docs, user docs

## 🐛 Known Limitations & Technical Debt

### MVP Limitations
- Simple role-based authorization (will need environment-specific roles later)
- Local authentication only (OAuth planned for Phase 2)
- No deployment approval workflows
- No automated notifications
- No CI/CD integration

### Planned Improvements (Phase 2)
- OAuth 2.0 integration (Azure AD, Okta)
- Environment-specific user permissions
- External dependencies tracking
- SLA management
- Automated deployment notifications
- Integration with CI/CD pipelines
- Advanced analytics and reporting

---

## 🤝 Contributing

### Code Standards
- Follow Spring Boot conventions for backend
- Follow Angular style guide for frontend
- Write meaningful commit messages
- Maintain test coverage thresholds
- Document all public APIs

### Git Workflow
1. Create feature branch: `feature/story-N-description`
2. Commit frequently with clear messages
3. Write/update tests
4. Create pull request
5. Address review comments
6. Merge to main after approval
