Making the changes get reflected

i do not have much experiece with working on development server started with docker. when we start devlopment enviormnet in traditional way using yarn start, we just need to save the changes and server get's restarted with updated code.

my simple query is if i start the volto project using "docker-compose up" command then if i make changes to the code afterwards, what do i need to do to start the devlopment server with updated code ? or the server automaticaly starts after saving the code, just like nodemon or yarn ?
