+Additional XBlocks that belong here
+***********************************
+
+Over time, more XBlocks may be moved here. An XBlock belongs here if and only if both of the following are true:
+
+1. **It needs to be part of the out-of-the-box Open edX experience, as agreed upon by the
+   Product Working Group.** Otherwise, perhaps the block belongs in `xblocks-extra <https://github.com/openedx/xblocks-extra>`_,
+   or it belongs in a community repository outside of the openedx GitHub organization.
+
+2. **The maintainers of this repository have capacity to maintain the additional block.**
+   Otherwise, perhaps the block belongs in its own repository with a separate dedicated maintainer,
+   such as `ora2 <https://github.com/openedx/edx-ora2>`_.
