3. Cross-Reference Best Practices

.. Use these reference styles

Classes and Methods
~~~~~~~~~~~~~~~~~~~

See :class:`mypackage.core.DataProcessor` for the main class.

Use :meth:`~mypackage.core.DataProcessor.process` method.

The :attr:`mypackage.core.DataProcessor.config` attribute.

Functions
~~~~~~~~~

Call :func:`mypackage.utils.helper` for utility functions.

Modules
~~~~~~~

Import from :mod:`mypackage.core` module.

External References
~~~~~~~~~~~~~~~~~~~

Uses :class:`numpy.ndarray` for array storage.

See :func:`pandas.read_csv` for file loading.
