+Install dependencies from Dependency Groups
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Python `Dependency Groups `_
+are a way of storing lists of dependencies in your ``pyproject.toml``.
+
+``pip`` version 25.1 and later, which is the default for Read the Docs builds,
+as well as many other tools support Dependency Groups.
+This example uses ``pip`` and installs from a group named ``docs``:
+
+.. code-block:: yaml
+ :caption: .readthedocs.yaml
+
+ version: 2
+
+ build:
+ os: ubuntu-24.04
+ tools:
+ python: "3.13"
+ jobs:
+ install:
+ - pip install --group 'docs'
+
+For more information on relevant ``pip`` usage, see the
+`pip user guide on Dependency Groups `_.
