-# Overview
-
 Datafiles is a bidirectional serialization library for Python [dataclasses](https://docs.python.org/3/library/dataclasses.html) that automatically synchronizes object instances to the filesystem using type annotations. It supports a variety of file formats with round-trip preservation of formatting and comments, where possible.
