        `feed_dict` dictionary key is used as a dataset name, and a value is used to create an instance of
        ``MemoryDataset`` before adding to the ``DataCatalog`` for all the value types except of ``AbstractDataset``.
        In the last case, the ``AbstractDataset`` is added as it is.

        Has `from_dict` alias, so it can be called using `from_dict` name instead.
        Will be fully renamed to `from_dict` in the `0.20.0` version.

        Args:
            feed_dict: A feed dict with data to be added to the ``DataCatalog``.
            replace: Specifies whether to replace an existing dataset with the same name in the ``DataCatalog``.

Review comment (suggestion):
I don't think we have a style guide for docstrings yet? In any case, following [Pydocstyle](http://www.pydocstyle.org/en/stable/error_codes.html) D404 and D401,

```suggestion
