+# Scan Control
+
+**Purpose:**
+
+The `ScanControl` widget is designed to generate a graphical user interface (GUI) to control various scan operations
+based on the scan's signature and `gui_config`. The widget is used to control the scan operations, such as starting,
+stopping, and pausing the scan. The widget also provides a graphical representation of the scan progress and the scan
+status. The widget is designed to be used in conjunction with the `ScanServer` and `ScanBundler` services from the BEC
+core services.
+
+By default the widget supports only the scans which have defined `gui_config` and are inhereted from these scan classes:
+
+- [ScanBase](https://beamline-experiment-control.readthedocs.io/en/latest/api_reference/_autosummary/bec_server.scan_server.scans.ScanBase.html)
+- [SyncFlyScanBase](https://beamline-experiment-control.readthedocs.io/en/latest/api_reference/_autosummary/bec_server.scan_server.scans.SyncFlyScanBase.html)
+- [AsyncFlyScanBase](https://beamline-experiment-control.readthedocs.io/en/latest/api_reference/_autosummary/bec_server.scan_server.scans.AsyncFlyScanBase.html)
+
+**Key Features:**
+
+- Automatically generates a control interface based on scan signatures and `gui_config`.
+- Supports adding and removing argument bundles dynamically.
+- Provides a visual representation of scan parameters grouped by functionality.
+- Integrates start and stop controls for executing and halting scans.
+
+**Example of Use:**

+**Code example:**
+The following code snipped demonstrates how to create a `ScanControl` widget using BEC Widgets within `BECIPythonClient`
