+# 说明
+
+该脚本按挖矿路线的效率从高到低挖矿，记录矿产资源的冷却时间，自动规划挖矿路线，可选挖矿种类和挖矿区域。
+
+- 目前支持5种运行模式
+  1. 最速480矿
+        
+        刷满480个矿石即停止
+
+  1. 挖指定数目的矿
+  
+        需要在下面的输入框中填一个数字，代表要挖矿的个数
+
+  1. 挖一段时间
+  
+        需要在下面的输入框中填一个数字，代表分钟数
+
+  1. 挖到某个时间点
+  
+        需要在下面的输入框中填一个停止挖矿的时间点，例如`3:55`、`23:30`等。若已过当前时间则代表第二天的该时间点，比如开始运行时间是`23:30`，填写`3:55`则表示一直挖矿到第二天的`3:55`。
+        
+        (WIP)也可以填一个时间段，例如`22:30~3:55`。若不在此时间段内则不会开始挖矿。
+
+  1. 挖所有矿 
+
+        顾名思义
+- 地面挖矿队伍中必须有诺艾尔，只挖水下的矿则无此限制
+- 矿产资源的冷却时间记录在脚本目录下`records/persistent_data.json`文件中，升级、重新订阅脚本或重新安装BetterGI可能导致该记录丢失，请自行备份。
