+## 使用示例
+
+### 1. 启动 Web API
+```bash
+dotnet run --project CodePlay.WebAPI/CodePlay.WebAPI.csproj --urls "http://localhost:5000"
+```
+
+### 2. 访问 Swagger
+```
+http://localhost:5000/swagger
+```
+
+### 3. 使用 CLI 工具
+```bash
+# 转换 C# 到 Java
+dotnet run --project CodePlay.CLI/CodePlay.CLI.csproj -- \
+  convert -s CSharp -t Java -i input.cs -o output.java
+
+# 查看历史报告
+dotnet run --project CodePlay.CLI/CodePlay.CLI.csproj -- \
+  list --project my-project
+
+# 验证转换结果
+dotnet run --project CodePlay.CLI/CodePlay.CLI.csproj -- \
+  check -i output.java -l Java
+```
+
+### 4. 启动前端
+```bash
+# Blazor + Known
+dotnet run --project CodePlay.WebUI/CodePlay.WebUI.csproj
+
+# Vue3 + ElementPlus
+cd CodePlay.Web && npm install && npm run dev
+```
