 For example, the directory with the backend code is mounted as a Docker "host volume" (in the file `docker-compose.dev.volumes.yml`), mapping the code you change live to the directory inside the container. That allows you to test your changes right away, without having to build the Docker image again. It should only be done during development, for production, you should build the Docker image with a recent version of the backend code. But during development, it allows you to iterate very fast.
 
-There is also a commented out `command` override (in the file `docker-compose.dev.command.yml`), if you want to enable it, uncomment it. It makes the backend container run a process that does "nothing", but keeps the process running. That allows you to get inside your living container and run commands inside, for example a Python interpreter to test installed dependencies, or start the development server that reloads when it detects changes.
+There is a command override in the file `docker-compose.dev.command.yml` that runs `/start-reload.sh` (included in the base image) instead of the default `/start.sh` (also included in the base image). It starts a single server process (instead of multiple, as would be for production) and reloads the process whenever the code changes. As it is in `docker-compose.dev.command.yml`, it only applies to local development. Have in mind that if you have a syntax error and save the Python file, it will break and exit, and the container will stop. After that, you can restart the container by fixing the error and running again:

+docker-compose up -d
