-The **Window** module provides basic capabilities for managing windows, including creating and destroying windows and setting serial port attributes.
+The `Window` module provides basic window management capabilities, such as creating and destroying the current window, setting properties for the current window, and managing and scheduling windows.
 
-> **NOTE**<br/>
+This module provides the following common window-related functions:
+
+- [Window](#window): the current window instance, which is the basic unit managed by the window manager.
+- [WindowStage](#windowstage9): window manager that manages windows.
