-OpenTelemetry Python SDK
-============================================================================
+OpenTelemetry Python Configuration Prototype
+============================================
 
-|pypi|
+This prototype first needs the ``src/opentelemetry/configuration/_interna/path_function.py``
+to be generated with the ``opentelemetry.configuration.render_schema`` function.
 
-.. |pypi| image:: https://badge.fury.io/py/opentelemetry-sdk.svg
-   :target: https://pypi.org/project/opentelemetry-sdk/
+Once this file is generated, implement the functions defined there.
 
-Installation
-------------
+To create any provider object first create a ``Resource`` object:
 
-::
+.. code-block:: python
 
-    pip install opentelemetry-sdk
+    from opentelemetry.configuration._internal.path_function import set_resource
+    from opentelemetry.configuration import (
+        resolve_schema,
+        process_schema,
+        create_object,
+        validate_configuration,
+    )
+    from pathlib import Path
