+Plugin add a selection function according to Virtools Group in Select menu.
 
-#### Select by Virtools Group
+This function firstly have 5 different selection strategies which is exactly matched with Blender selection method. Just use it like Blender selection (Set, Extend, Subtract, Invert, Intersect).  
+Then, select your group name to start a selection.
 
-Select objects in active collection according to its Virtools Group properties.  
+If you can, using Subtract or Intersect modes would be better than other modes. Because these modes avoid analyzing too many objects.
-The hidden object also can be selected if you check `Ignore Hide Property`.  
+For example, first, select a rough range, and then use the Intersect mode to filter objects, which is more efficient than directly using the Start mode to select.
-Check `Merge Selection` will merge current selection and previous selection.
-
-#### Filter by Virtools Group
-
-Filter current selected object by its Virtools Group properties.  
-Check `Reverse` remove objects matching the requirements, not keep them.

+该功能首先有5种不同的选择策略，与Blender的选择方法完全匹配（开始、扩选、相减、反转、相交）。只需像Blender选择那样使用它。
+然后，选择你需要的组的名称，然后开始一次选择或筛选。
 
-将对当前活动集合内的物体按照其Virtools Group属性进行选择。  
+如果可以，请尽可能使用相减或相交模式。因为这样可以避免分析过多的物体。  
-勾选`Ignore Hide Property`后，即使是隐藏的物体，也会被筛选。  
+例如先选定一个大致的范围，然后使用相交模式过滤，比直接使用开始模式效率更高。
-勾选`Merge Selection`，将会把选中的物体合并到当前选定的内容中。
