 The `--watch` parameter starts containers with the `hot-reload` feature. This enables the auto-reload functionality, meaning that the container will be automatically reloaded when the code for either the frontend or backend changes.
 
 > The `hot-reload` feature for backend applications uses `dotnet watch`, which only detects changes to existing files. It will not restart the container if new files are added (dotnet watch [issue](https://github.com/dotnet/aspnetcore/issues/8321)).
