+Username Query Parameter
+--------------------------
+
+An alternative way to access the application is by using the ``username`` query parameter. This allows for automatic configuration of the Username input and automatically searches. Additionally, when the ``username`` parameter is sent, the accordion with the filters will already be open.
+
+Example URL format:
+
+``https://waybacktweets.streamlit.app?username=<USERNAME>``
