+
+## 使用示例
+
+### 基本使用
+
+```go
+// 创建游戏机器人
+bot, err := NewLLKGameBot("android", "")
+if err != nil {
+    log.Fatal(err)
+}
+defer bot.Close()
+
+// 分析游戏界面
+gameElement, err := bot.AnalyzeGameInterface()
+if err != nil {
+    log.Fatal(err)
+}
+
+// 创建求解器并查找配对
+solver := NewLLKSolver(gameElement)
+pairs := solver.FindAllPairs()
