It can't cover every edge case, so if you need more information about any of these elements, refer to the reference guides for [basic syntax](https://www.markdownguide.org/basic-syntax/) and [extended syntax](https://www.markdownguide.org/extended-syntax/). ## Basic Syntax These are the elements outlined in John Gruber’s original design document.
