Add docstrings to config module #2

	# A check to ensure that our docstring coverage remains pretty good.
	#
	# We use interrogate (https://interrogate.readthedocs.io/) to check
	# docstring coverage. Settings are under `[tool.interrogate]` section
	# of the pyproject.toml file in the top-level directory.
