-   In June 2023, **pydantic v2** was released. This introduced backwards
-   incompatible API and behavioral changes in comparison to pydantic v1. Hence,
-   **autodoc_pydantic** required substantial adjustments, too. In order to keep
-   the codebase clean and concise, separate versions for v1 and v2 were
-   created. The v2 branch will eventually become the new `main`_ branch while
-   the code for v1 remains in the `main-1.x`_ branch.
-
-   In a nutshell, if you want to work on v1, please checkout the corresponding
-   `main-1.x`_ branch. Otherwise, refer to the `main`_ branch.

+(see `here <https://tox.wiki/en/latest/installation.html>`_):
+
+Second, to invoke the test suite with tox, run one of the following commands:
 
-- Test a specific environment: ``poetry run tox -e py38-pydantic17-sphinx34``
-- Test the latest stable versions from pypi: ``poetry run tox -e latest``
-- Test the current developer versions from git repositories: ``poetry run tox -e development``
-- Test all available environments: ``poetry run tox`` (not recommended)
