Adding Documentation

There are a few guidelines when adding new documentation, or when refactoring the current documentation.

• We use the numpy docstring format <https://numpydoc.readthedocs.io/en/latest/format.html>.

• Code examples or example yaml files should be tested using the sphinx extension doctest.

• New APIs should be added to the docs/api folder. The builtin autosummary and toctree are used to keep track.
