+## Stages
+
+Some type of templates(Item, Note) support stages.
+
+Code wrapped inside the stage will be called at a specific time.
+
+For example, the `beforeloop` stage code:
+
+```js
+// @beforeloop-begin
+code;
+// @beforeloop-end
+```
+
+| stage      | calling time                      |
+| ---------- | --------------------------------- |
+| beforeloop | before entering the loop of items |
+| default    | loop of items                     |
+| beforeloop | after leaving the loop of items   |
+
+In other type of templates, the default stage is called.
