The help text for --env-file no longer mentions that there's a default value of env/local.env. Consider updating the help text to inform users about the default behavior, e.g., help='the env file with the deployment-specific variables (default: env/local.env)'

Suggested change

	help='the env file with the deployment-specific variables'
	help='the env file with the deployment-specific variables (default: env/local.env)'

The comment references hardcoded volume names 'simoc_db-testing' and 'simoc_db-data', but the actual volume names are now dynamic based on PROJECT_NAME. Consider updating the comment to reflect this, e.g., "mount the '{PROJECT_NAME}_db-testing' volume instead of the default '{PROJECT_NAME}_db-data' if 'testing' is passed as arg"

Suggested change

	# mount the 'simoc_db-testing' volume instead of the
	# default 'simoc_db-data' if 'testing' is passed as arg
	# mount the '{PROJECT_NAME}_db-testing' volume instead of the
	# default '{PROJECT_NAME}_db-data' if 'testing' is passed as arg
