+# User Script Widget
+
+````{tab} Overview
+
+The [`UserScriptWidget`] is designed to allow users to run their user-defined scripts directly from a BEC GUI. This widget lists all available user scripts and allows users to execute them with a single click. The widget also provides an interface to open a VSCode editor to modify the files hosting the user scripts. This widget is particularly useful to provide a user-friendly interface to run custom scripts to users without using the command line. We note that the scripts are executed in a BEC client that does not share the full namespace with the BEC IPython kernel.
+
+## Key Features:
+- **User Script Execution**: Run user-defined scripts directly from the BEC GUI.
+- **VSCode Integration**: Open the VSCode editor to modify the files hosting the user scripts.
+
+
+````{tab} Examples
+
+The `UserScriptWidget` widget can be integrated within a [`BECDockArea`](user.widgets.bec_dock_area) or used as an individual component in your application through `BECDesigner`. Below are examples demonstrating how to create and use the `BECStatusBox` widget.
+
+## Example 1 - Adding BEC Status Box to BECDockArea
+
+In this example, we demonstrate how to add a `BECStatusBox` widget to a `BECDockArea`, allowing users to monitor the status of BEC processes directly from the GUI.
+
+```python
+# Add a new dock with a BECStatusBox widget
+user_script = gui.add_dock().add_widget("UserScriptWidget")
+```
+
+```{hint}
+The widget will automatically display the list of available user scripts. Users can click on the script name to execute it.
+```
