+
+This document provides instructions on how to use the `impactx-dashboard`.
+

+
+Launching the Dashboard
+-----------------------
+
+There are two ways to launch the Dashboard GUI, depending on your use case:
+
+- **Using the CLI Command**: This is the recommended method for most users. It is straightforward and requires minimal setup.
+- **Using the Python Module**: This method is more flexible and is particularly useful for developers who need to make direct 
+changes to the dashboard, integrate it with other Python scripts, or run it in a specific environment.
+
+1. **Direct Command Execution**  
+   From the base ImpactX directory, execute:
+
+   .. code-block:: bash
+
+      impactx-dashboard
+
+2. **Python Module Execution**  
+   From the `impactx/src/python/impactx` directory, execute:
+
+   .. code-block:: bash
+
+      python -m dashboard
+
+3. **Access the GUI**  
+
+   Open a web browser and navigate to `http://localhost:8080` to access the Dashboard GUI.
