 ### How does the local node server throttle the upload requests?
 
-The local node server throttles the upload requests to simulate a real world scenario on a cellular connection or slower network. This helps test out the progress and timeout handling on the client. It does this by using the node `throttle` library. See the `/upload` route in [here](example/server/server.ts) for the details.
