# 📄 Documentation & Reference Models
|
|
|
|
This `/docs` folder contains **Product Requirements Documents (PRD)**, **data model definitions**, and **Firebase schema references** for the Karaoke App project.
|
|
|
|
These files are intended for:
|
|
- 📃 Developers reviewing the business logic and architecture.
|
|
- 🤖 AI tools like Cursor or Copilot that reference documentation for context-aware coding.
|
|
- 📝 Project planning, architecture decisions, and future enhancements.
|
|
- 🚀 **Building the app from scratch with any framework/platform combination.**
|

|
|
| File | Purpose |
|
|
|------|---------|
|
|
| `PRD.md` | **Complete Product Requirements Document** — platform-agnostic business logic, technical specifications, data flows, service APIs, component architecture, error handling, and performance optimizations. **Self-guiding for AI implementation.** |
|
|

## 🚀 How to Use This Documentation
|
|
|
|
### **For AI-Assisted Development:**
|
|
Simply say **"Read this PRD"** in any new chat. The PRD contains:
|
|
- **Self-guiding instructions** for AI implementation
|
|
- **Complete technical specifications** for 100% accuracy
|
|
- **Implementation questions** to determine platform/framework choices
|
|
- **Step-by-step build process** with checklists
|
|
|
|
### **For Human Developers:**
|
|
- **Reference during implementation** for business logic and data flows
|
|
- **Guide for architecture decisions** and technology choices
|
|
- **Source of truth** for all functional requirements
|
|
- **Migration guide** when switching frameworks/platforms
|
|
|
|
### **For New Implementations:**
|
|
1. **Read the PRD completely** - it contains comprehensive specifications
|
|
2. **Answer implementation questions** from Section 29
|
|
3. **Follow the implementation checklist** for complete build process
|
|
4. **Preserve business logic** while adapting UI to chosen framework

## 🔄 Workflow for New Versions
|
|
|
|
### **When Creating New Implementations:**
|
|
1. **Use the PRD as-is** - it's designed for any framework/platform
|
|
2. **Follow the implementation guide** in Section 29
|
|
3. **Preserve all business logic** while adapting UI layer
|
|
4. **Test against specifications** for 100% accuracy
|
|
|
|
### **When Updating the PRD:**
|
|
1. **Keep platform-agnostic requirements** intact
|
|
2. **Add new implementation details** to appropriate sections
|
|
3. **Update toolset sections** with new technology choices
|
|
4. **Maintain self-guiding nature** for AI implementation
|
|
|
|
### **When Migrating Platforms:**
|
|
1. **Keep all business logic** from core requirements
|
|
2. **Replace only implementation details** in platform-specific sections
|
|
3. **Add new platform sections** following the established pattern
|
|
4. **Update toolset rationale** for new technology choices
|

## Important Notes
|
|
- ✅ These files are **not intended for direct import or use in application runtime**.
|
|
- ✅ Validation logic and data models here serve as **development references only**.
|
|
- ✅ Any updates to business logic, data flow, or app architecture should be reflected here for documentation purposes.
|
|
- ✅ AI tools may use this information to assist with code generation but will not access `/src` directly.
|
|
- ✅ **The PRD is self-guiding** - it contains all instructions needed for AI implementation.
|
|
- ✅ **100% accuracy achievable** when following the complete specifications.
