+Show the inheritance diagram of a class using [Mermaid](https://mermaid.js.org/).
+
+With this option enabled, an inheritance diagram (as a flowchart)
+will be displayed after a class signature.
+Each node will act as a cross-reference
+and will bring you to the relevant class' documentation
+when clicking on it.
+
+It should work out of the box with [Material for MkDocs][].
+For other themes, you must include Mermaid's Javascript code manually:

+Whether to render headings for function/method parameters.
+
+With this option enabled, each function/method parameter
+(including parameters of `__init__` methods merged in their parent class
+with the [`merge_init_into_class`][] option)
+gets a permalink, an entry in the Table of Contents,
+and an entry in the generated objects inventory.
+The permalink and inventory entry allow cross-references
+from internal and external pages.
+
+The identifier used in the permalink and inventory is of the following form:
+`path.to.function(param_name)`. To manually cross-reference a parameter,
+you can therefore use this Markdown syntax:
+
+```md
+- Class parameter: [`param`][package.module.Class(param)]
+- Method parameter: [`param`][package.module.Class.method(param)]
+- Function parameter: [`param`][package.module.function(param)]
+- Variadic positional parameters: [`*args`][package.module.function(*args)]
+- Variadic keyword parameters: [`**kwargs`][package.module.function(**kwargs)]
+```
+
+Enabling this option along with [`signature_crossrefs`][] will automatically
+render cross-references to parameters in class/function/method signatures
+and attributes values.

+
+Modernize annotations with latest features and PEPs of the Python language.
+
+The Python language keeps evolving, and often library developers
+must continue to support a few minor versions of Python.
+Therefore they cannot use some features that were introduced
+in the latest versions.
+
+Yet this doesn't mean they can't enjoy latest features in their docs:
+Griffe allows to "modernize" expressions, for example
+by replacing `typing.Union` with [PEP 604][pep-604] type unions `|`.
+Thanks to this, mkdocstrings' Python handler
+can automatically transform type annotations into their modern equivalent.
+This improves consistency in your docs, and shows users
+how to use your code with the latest features of the language.
+
+[pep-604]: https://peps.python.org/pep-0604/
+
+Modernizations applied:
+
+- `typing.Dict[A, B]` becomes `dict[A, B]`
+- `typing.List[A]` becomes `list[A]`
+- `typing.Set[A]` becomes `set[A]`
+- `typing.Tuple[A]` becomes `tuple[A]`
+- `typing.Union[A, B]` becomes `A | B`
+- `typing.Optional[A]` becomes `A | None`
