.. _Teak Design Tokens:

Design Tokens (New Theming System)
##################################

In Ulmo, Design Tokens - a new way of comprehensive theming - will debut. This
theming system makes it much easier to theme your full site, including the Open
edX mobile applications.

.. warning::

    Open edX site operators should be sure to follow the :ref:`Ulmo Design
    Tokens` page for updates on the upcoming changes. There will be no overlap
    between the old theming system and Design Tokens, so site operators will
    need to prepare for the changes in advance of the Ulmo release.

    Operators *will* be able to test their implementation of Design Tokens using
    the `teak-design-tokens` branches in the Tutor-supported MFE repos. For more
    information, see the `Teak design tokens wiki page
    <https://openedx.atlassian.net/wiki/spaces/BPL/pages/5050499077/Using+Teak+Design+Tokens+branches>`_.

See this presentation from the November 2024 Open edX meetup for more detail.
