-The motivation for this change is to drive adoption, contribution, and improvement of the Open edX platform mobile experiences. The existing mobile applications were authored in 2015 and are not broadly used across the open edx ecosystem today. Improvements to architectural patterns, development languages, and mobile operating systems have transformed mobile development in ways that make it difficult for our existing code bases to adopt quickly. The Racoon Gang mobile team rebuilt and open sourced new ios and android applications that form a strong architectural basis on which to continue community development of the mobile applications.

 * The new repositories will be migrated to the ``openedx`` github organization under the names ``openedx-app-ios`` and ``openedx-app-android``.
 * The new repositories will be maintained in accordance with OEP-55.
 * Relevant funded contributions and projects relation to the new mobile repositories will be linked from their main project README as a way to help community members find ongoing and future efforts.
+* In support of a consistent platform-wide branding interface, the mobile experiences will strive to identify opportunities to consume and extend the Paragon design system, helping to ensure consistent and maintainable UX across channels (i.e., mobile, web).
