 The new MyST architecture was very appealing for several reasons:
 - **Sustainability**: Our current Sphinx-based architecture was becoming clunky and hard to maintain as members joined or left the project, and required too much boilerplate code in individual cookbook repos which presented a barrier to would-be new contributors. MyST offered a much more streamlined alternative to keep our community project growing.
 - **Staying on the leading edge of best practices**: We are an open-source community resource that teaches open-source coding practices, so it’s important that our own sites continue to be useful models for the broader community.
-- **Making cookbooks better!** A lot of the new functionality in MyST is really well suited to the cookbooks, including things like [cross-referencing](https://mystmd.org/guide/cross-references) and [embedding content](Embed & Include Content - MyST Markdown) and automated [bibliographies](https://mystmd.org/guide/citations).

 - **Cross-pollination with the core developers!** Having the MyST developers invested in our use-case as a demo as they learn, understand, and develop functionality that will be particularly useful to us (and users that come after) is a really nice feedback loop from both a community and technological stand point.
