+Building DTS API docs
+---------------------
+
+To build DTS API docs, install the dependencies with Poetry, then enter its shell:
+
+.. code-block:: console
+
+ poetry install --no-root --with docs
+ poetry shell
+
+The documentation is built using the standard DPDK build system.
+After executing the meson command and entering Poetry's shell, build the documentation with:
+
+.. code-block:: console
+
+ ninja -C build dts-doc
+
+The output is generated in ``build/doc/api/dts/html``.
+
+.. Note::
+
+ Make sure to fix any Sphinx warnings when adding or updating docstrings,
+ and also run the ``devtools/dts-check-format.sh`` script and address any issues it finds.
