 ## 使用
 
-* 遙控器左鍵/觸屏單擊打開節目列表
+* 遙控器左鍵/觸屏單擊打開視頻列表
 * 遙控器右鍵/觸屏雙擊打開配置
-* 遙控器返回鍵關閉節目列表/配置
-* 打開配置頁后，選擇遠程配置，掃描二維碼可以配置視頻源地址等。
-* 如果視頻源地址已配置，並且打開了“啟動后自動更新視頻源”后，軟件啟動后自動更新視頻源
-* 在節目列表顯示的時候，右鍵收藏/取消收藏

+* 打開配置后，選擇遠程配置，掃描二維碼可以配置視頻源等。也可以直接遠程配置地址 http://0.0.0.0:34567
+* 如果視頻源地址已配置，並且打開了“應用啟動后更新視頻源”后，應用啟動后會自動更新視頻源
