Install this package via pip:

pip install sphinxcontrib-kroki

and enable in project configuration (conf.py):

extensions = [
    'sphinxcontrib.kroki',
]

Inline diagram, show as svg:

.. kroki::
   :caption: Diagram

    @startuml
    Alice -> Bob: Authentication Request
    Bob --> Alice: Authentication Response

    Alice -> Bob: Another authentication Request
    Alice <-- Bob: Another authentication Response
    @enduml

.. kroki:: ./path/to/graph.puml png

• :align: The horizontal alignment of the diagram (left, center or right);
