+
+# Npgsql 다운로드
+cd ThirdParty
+mkdir Npgsql
+cd Npgsql
+nuget install Npgsql -Version 6.0.11 -Framework netstandard2.1
+
+# DLL 파일 복사
+cp Npgsql.6.0.11/lib/netstandard2.1/*.dll ./
+cp System.Buffers.*/lib/netstandard2.1/*.dll ./
+cp System.Memory.*/lib/netstandard2.1/*.dll ./
+cp System.Runtime.CompilerServices.Unsafe.*/lib/netstandard2.1/*.dll ./
+cp System.Threading.Tasks.Extensions.*/lib/netstandard2.1/*.dll ./
+
+# 임시 폴더 삭제
+rm -rf Npgsql.6.0.11/ System.Buffers.*/ System.Memory.*/ System.Runtime.CompilerServices.Unsafe.*/ System.Threading.Tasks.Extensions.*/
+```
+
+**Option 3: 수동 다운로드**
+
+1. https://www.nuget.org/packages/Npgsql/6.0.11 접속
+2. 오른쪽 "Download package" 클릭
+3. `.nupkg` 파일을 `.zip`으로 이름 변경
+4. 압축 해제
+5. `lib/netstandard2.1/` 폴더의 DLL 파일들을 `ThirdParty/Npgsql/`에 복사
+
+#### 최종 폴더 구조:
+
+```

+
+---
+
+## ✅ 설치 확인

+1. Unity Editor 재시작
+2. `Console` 탭에서 DLL 로딩 에러 확인
+3. 메뉴: `Tools > Unity Editor Toolkit > Server Window`
+4. Database 탭 확인 (Phase 1 완료 후 표시됨)
+
+---
+
+## 🔧 문제 해결
+
+### DLL 충돌 에러
+
+```
+Assembly 'Npgsql' has already been loaded from a different location.
+```
+
+**해결:**
+1. Unity 프로젝트의 `Packages/` 폴더에서 중복 Npgsql 제거
+2. `Library/ScriptAssemblies/` 삭제
+3. Unity Editor 재시작
+
+### .NET Standard 2.1 호환성 에러
+
+```
+The type or namespace name 'System.Buffers' could not be found
+```
+
+**해결:**
+1. Unity 2020.3 이상 사용 확인
+2. `Edit > Project Settings > Player > Other Settings`
+3. `Api Compatibility Level`: `.NET Standard 2.1` 선택
+4. Unity Editor 재시작
+
+### UniTask 중복 에러
+
+```
+Multiple precompiled assemblies with the same name UniTask.dll
+```
+
+**해결:**
+- Option 1 (UPM) 사용 시 Option 3 (수동 DLL) 제거
+- 또는 반대

+# websocket-sharp DLL Installation
+
+Unity Editor Toolkit requires websocket-sharp for WebSocket communication.
+
+## Installation Steps
+
+### Step 1: Download websocket-sharp
+
+**Option A: Download Pre-built DLL (Recommended)**
+
+1. Go to: https://github.com/sta/websocket-sharp/releases
+2. Download the latest release (e.g., `websocket-sharp.zip` or `websocket-sharp.dll`)
+3. Extract if needed
+
+**Direct Download Link:**
+- Latest stable: https://github.com/sta/websocket-sharp/releases/download/1.0.3-rc11/websocket-sharp.dll
+
+**Option B: Build from Source**
+
+```bash
+git clone https://github.com/sta/websocket-sharp.git
+cd websocket-sharp/websocket-sharp
+# Build with your C# compiler or Visual Studio
+```
+
+### Step 2: Add DLL to Unity Project
+
+**Copy the DLL to this exact location:**
+
+```
+Packages/com.devgom.unity-editor-toolkit/ThirdParty/websocket-sharp/websocket-sharp.dll
+```
+
+**Full Path Examples:**
+
+**Windows:**
+```
+D:\YourUnityProject\Packages\com.devgom.unity-editor-toolkit\ThirdParty\websocket-sharp\websocket-sharp.dll
+```
+
+**macOS/Linux:**
+```
+/Users/YourName/UnityProjects/YourProject/Packages/com.devgom.unity-editor-toolkit/ThirdParty/websocket-sharp/websocket-sharp.dll
+```
+
+### Step 3: Configure Import Settings in Unity
+
+1. Unity will automatically detect the DLL
+2. Select `websocket-sharp.dll` in Project window
+3. In Inspector, verify settings:
+   - **Any Platform**: ✓ Checked
+   - **Editor**: ✓ Include
+   - **Standalone**: ✗ Exclude (Editor only)
+
+4. Click **Apply**
+
+### Step 4: Verify Installation
+
+**Method 1: Check Console**
+
+After adding the DLL, Unity should not show any import errors. Check Console (Ctrl+Shift+C) for:
+- ✓ No "missing assembly" warnings
+- ✓ No websocket-sharp related errors
+
+**Method 2: Test Server**
+
+1. Create GameObject → Add `UnityEditorServer` component
+2. Enter Play Mode
+3. Console should show: `✓ Unity Editor Server started on ws://127.0.0.1:9500`
+
+## Troubleshooting
+
+### Error: "Assembly 'websocket-sharp' not found"
+
+**Solution:**
+- Verify DLL is in correct location: `ThirdParty/websocket-sharp/websocket-sharp.dll`
+- Restart Unity Editor
+- Reimport package: Right-click package → Reimport
+
+### Error: "Could not load file or assembly"
+
+**Solution:**
+- Check DLL platform settings (Any Platform should be checked)
+- Try different websocket-sharp version
+- Ensure you're using .NET Framework 4.x (not .NET Standard)
+
+### DLL Not Appearing in Project Window
+
+**Solution:**
+1. Close Unity
+2. Delete `Library/` folder in your project
+3. Reopen Unity (will reimport all assets)
+
+### Unity 2020.3+ Compatibility
+
+websocket-sharp 1.0.3-rc11 is compatible with:
+- Unity 2020.3 LTS
+- Unity 2021.3 LTS
+- Unity 2022.3 LTS
+- Unity 6 (2023.2+)
+
+## Alternative: NuGet for Unity
+
+If you have NuGet for Unity installed:
+
+1. Install NuGet for Unity: https://github.com/GlitchEnzo/NuGetForUnity
+2. Open NuGet window: `NuGet → Manage NuGet Packages`
+3. Search: "websocket-sharp"
+4. Click **Install**
+
+**Advantages:**
+- Automatic dependency management
+- Easy updates
+- No manual DLL copying
+
+**Disadvantages:**
+- Requires additional package (NuGet for Unity)
+- Slightly larger project size
+
+## File Structure After Installation
+
+```
+Packages/com.devgom.unity-editor-toolkit/
+├── ThirdParty/
+│   └── websocket-sharp/
+│       ├── websocket-sharp.dll          ← You add this

+│       └── README.md                    ← This file
+├── Runtime/
+├── Editor/
+└── ...
+```
+
+## Verification Checklist
+
+- [ ] DLL downloaded from official source
+- [ ] DLL placed in `ThirdParty/websocket-sharp/` folder
+- [ ] Unity detected and imported DLL (no Console errors)
