 ## Design principles
 
 Maintainers of Jupyter AI have adopted principles that contributors should also follow. These principles, which build on top of [the Zen of Python](https://peps.python.org/pep-0020/), are intended to earn users' trust by keeping their data under their control. The following list is non-exhaustive; maintainers have discretion to interpret and revise these principles.

+# Developers
+
+The developer documentation is for authors who want to enhance
+the functionality of Jupyter AI.
+
+If you are interested in contributing to Jupyter AI,
+please see our {doc}`contributor's guide </contributors/index>`.
+
+## Pydantic compatibility
+
+Jupyter AI is fully compatible with Python environments using Pydantic v1
+or Pydantic v2. Jupyter AI imports Pydantic classes from the
+`langchain.pydantic_v1` module. Developers should do the same when they extend
+Jupyter AI classes.
+
+For more details about using `langchain.pydantic_v1` in an environment with
+Pydantic v2 installed, see the
+[LangChain documentation on Pydantic compatibility](https://python.langchain.com/docs/guides/pydantic_compatibility).

+Jupyter AI internally uses Pydantic v1 and should work with either Pydantic
+version 1 or version 2. For compatibility, developers using Pydantic V2
+should import classes using the `pydantic.v1` package. See the
