What makes this work on Railway?

For this project to run on Railway I have added a railway.json file with a custom start command, let me break the start command down:

streamlit run Hello.py tells streamlit to run Hello.py
--server.address 0.0.0.0 listen on host 0.0.0.0 so that streamlit is accessible externally
--server.port $PORT configures streamlit to listen on the auto assigned PORT variable that railway expects the app to listen on
--server.fileWatcherType none turns off the file watcher, code changes can't be made after the deployment so starting a file watcher uses unnecessary resources and can cause instabilities
--browser.gatherUsageStats false disables telemetry reporting
--client.showErrorDetails false disables showing debug messages in the browser
--client.toolbarMode minimal removes the 3-dot debug menu from the deployed site

Documentation for additional configurations can be found here

I have also updated the dependencies in the requirements.txt file, and added a .python-version file that tells Railway to build this project with Python 3.10
