+
+</center>
+
+你可以选择变量后使用快捷键 `alt` + `c` 自动生成控制台语句，也可以使用 `ctrl` + `alt` + `c` 删除文件的控制台语句。
+
+你还可以使用 `命令面板`，搜索 `Add Tree Log` 来生成它们，或者搜索 `Delete Tree Log` 来删除。
+
+当然，你也可以在选择变量后右键，选择 `Tree Log` 进行操作。
+
+
+
+## 设置
+
+你可以通过 `Settings.json` 添加文本，来自定义树头（命令面板 -> 首选项：打开设置 (JSON)）
+
+比如:
+
+* `tree-log.suffix`: "a custom text"
