 ## 编译与运行
+
+### Windows PowerShell编码设置 (重要)
+> **注意**：在Windows PowerShell控制台运行程序前，请先执行以下命令设置编码，否则可能导致中文显示错误或运行的异常：
+> ```powershell
+> [Console]::InputEncoding = [Console]::OutputEncoding = [System.Text.Encoding]::UTF8
+> ```
+
+### 通过源代码编译运行
 1. 编译：`javac -d out src/*.java`
 2. 运行：`java -cp out Main`
 
+### 通过JAR包运行
+1. 直接运行JAR包：`java -jar out/artifacts/relentless1_jar/relentless1.jar`
+
 ## 注意事项
 1. 题目数量必须在10-30之间，否则会提示重新输入
 2. 切换难度时，请确保输入格式正确：`切换为 级别名称`
