 This page is rendered from [github-flavored markdown](https://docs.github.com/en/get-started/writing-on-github/getting-started-with-writing-and-formatting-on-github/basic-writing-and-formatting-syntax) and passing the content through [react-markdown](https://github.com/remarkjs/react-markdown) to [Instructure UI](https://instructure.design/).  The result is accessible, well styled, and modular content created simply with markdown.
