 A editor written for TAS file editing.
 
+## Deprecation Note
+
+I have lost all my interests on this game, Ballance, since 1 year ago. However, recently, I noticed that there were some improvements and modifications in Ballance TAS. What I want to clarified is that I have no intention on updating this project to adapt the new format or feature of Ballance TAS. So I archive this repository to explicitly indicate this standpoint.
+
+However, this status is not prepetual. I will reopen this repository until I have learned enough text editor skills, such as Gap Buffer, to improve this application, or, restored the interests on this game (barely but still possible). You can freely fork this repository, or create new Ballance TAS editor on your own. That's your right granted by open source license.

 一款专门用于编辑Ballance TAS文件的编辑器
 
+## 弃用说明
+
+一年前，我对 Ballance 这款游戏失去了兴趣。然而，最近，我注意到 Ballance TAS 有一些改进和修改。我想澄清的是，我无意更新这个项目以适应 Ballance TAS 的新格式或功能。所以我存档了这个存储库以明确表明这一立场。
+
+但是，这种状态不是永久的。我将重新打开这个存储库，直到我学会了足够的文本编辑器技能（例如 Gap Buffer）来改进这个应用程序，或者恢复对这个游戏的兴趣（勉强但仍然可能）。您可以自由地分叉这个存储库，或者自己创建新的 Ballance TAS 编辑器。这是开源许可证授予您的权利。
