+        提交前请确认：
+        * 该问题确实是 **HMCL 的错误**，而**不是 Minecraft 非正常退出**，如果你的 Minecraft 非正常退出，请前往 [QQ 群](https://docs.hmcl.net/groups.html)/[Discord 频道](https://discord.gg/jVvC7HfM6U) 中获取帮助。
+        * 你的启动器版本是**最新的快照版本**，可以点击 [此处](https://zkitefly.github.io/HMCL-Snapshot-Update/) 下载最新快照版本。
+    
+        如果你的问题并不属于上述两类，你可以选取另一种 Issue 类型，或者直接前往 [QQ 群](https://docs.hmcl.net/groups.html)/[Discord 频道](https://discord.gg/jVvC7HfM6U) 中获取帮助。
+        
+        Before submitting, please confirm:
+        * The issue is indeed **an error of HMCL**, not **Minecraft abnormal exit**. If your Minecraft exits abnormally, please go to the [QQ group](https://docs.hmcl.net/groups.html) or [Discord channel](https://discord.gg/jVvC7HfM6U) for help.
+        * Your launcher version is **the latest snapshot version**. You can click [here](https://github.com/burningtnt/HMCL-Snapshot-Update/raw/master/datas/HMCL-dev.jar) to download the latest snapshot version.
+        
+        If your issue does not fall into the above two categories, you can choose another type of issue or directly go to the [QQ group](https://docs.hmcl.net/groups.html) or [Discord channel](https://discord.gg/jVvC7HfM6U) for help.
