+## 課題内容
+タイピングゲームを作ろう
+- 標準出力に英単語を出す（出すものは自由）
+- 標準入力から1行受け取る
+- 制限時間内に何問解けたか表示する
+
+## 実行例
+```$xslt
+$ typing-game 
+【タイピングゲーム】画面に表示される英単語をできるだけ多く入力しましょう！
+制限時間は10秒です。
+1問目: apple
+>apple
+正解！ 現在の正答率:1/1
+2問目: bake
+>bake
+正解！ 現在の正答率:2/2
+3問目: cup
+>cup
+正解！ 現在の正答率:3/3
+4問目: dog
+>cat
+不正解... 現在の正答率:3/4
+5問目: egg
+>
+タイムアップ！
+***
+4問中3問正解
+***
+お疲れ様でした！
+```
+
+## その他
+- 制限時間や問題等が固定になっているので可変にしたい
+- テストパッケージを分けたい
