+# Excel KV Middleware & Schema Editor
+
+복잡한 구조의 엑셀 데이터를 고성능 Key-Value Store(**Microsoft Garnet**)에 적재하고, 표준 스키마를 정의/편집하는 시스템입니다.
+
+## 🚀 Key Features
+
+### 1. High-Performance Ingestion
+- **Pure .NET 8.0**: Python 등 외부 의존성 없는 단일 플랫폼.
+- **Embedded Garnet**: Redis 호환 고성능 인메모리 스토어 내장.
+- **2D Flattening**:
+  - 병합된 Cross-Tab 엑셀 헤더를 논리적 Key로 자동 평탄화.
+  - Key Format: `{Sheet}:{LeftAxis}*{TopAxis}` (예: `Station.No1*Concrete.TypeA`)
+
+### 2. Smart Schema Management
+- **Interactive Region**: 헤더와 데이터 영역을 동적으로 지정 가능 (`RegionConfig`).
+- **Unmerge & Fill**: 병합된 셀을 자동으로 분리하여 데이터 컨텍스트 유지.
+- **SI Unit System**: 물리적 단위(`m`, `m3`, `kg`)를 코드 레벨(`SiUnit` Enum)에서 엄격하게 관리.
+
+### 3. Editor UI (In Progress)
+- **Blazor Web App**: 웹 기반의 협업 가능한 스키마 편집기.
+- **CRDT Sync**: 다수 사용자가 동시 편집 시 충돌 없는 병합 지원 예정.
+
+## 🛠 Project Structure
+
+- **`ExcelKv.Core`**: 핵심 로직 라이브러리 (SI Unit, ExcelLoader, SchemaRegistry).
+- **`ExcelKvPoC`**: 데이터 파싱 및 적재 검증용 콘솔 앱.
+- **`SchemaEditor`**: 표준 스키마 편집용 Blazor 웹 애플리케이션.
+
+## 🚦 Getting Started
+
+### Prerequisites
+- .NET SDK 8.0+
+
+### Run PoC (Excel Ingestion)
+```bash
+dotnet run --project ExcelKvPoC
+```
+- 실행 시 `sample.txt`에 파싱된 Key-Value 결과가 출력됩니다.
+
+### Run Editor (Blazor)
+```bash
+dotnet run --project SchemaEditor
+```
+
+## 📝 Roadmap
+- [x] Excel Parsing & 2D Flattening
+- [x] Garnet Integration (Embedded)
+- [x] SI Unit System Definition
+- [ ] Blazor Editor UI Implementation
+- [ ] CRDT Synchronization Layer
