I installed Streamlit for the first time and successfully launched its demo application in my browser. This helped me confirm that Python, Streamlit, and my development environment were set up correctly. I also explored the example pages in the sidebar to understand how Streamlit can display text, dataframes, charts, maps, and animations. This is the first technical milestone for my lost-and-found project. Next, I will replace the demo screen with the first interface for my own application.
