+paxb is a library that provides an API for mapping between XML documents and Python objects.
+
+paxb library implements the following functionality:
+
+- :doc:`Deserialize <paxb/deserialization>` XML documents to Python objects
+- Validate deserialized fields
+- Access and update Python object fields
+- :doc:`Serialize <paxb/serialization>` Python objects to XML documents
+
+paxb provides an efficient way of mapping between an XML document and a Python object. Using paxb
+developers can write less boilerplate code emphasizing on application domain logic.
+
+As soon as paxb is based on `attrs <https://www.attrs.org/en/stable/index.html>`_ library paxb and attrs
+API can be :doc:`mixed <paxb/attrs>` together.
