Markdown sneak peek: Summary

Important

Make sure a new line (space) exists between text and the first list item. For sublists or nested lists, indent four spaces to create a new level in the list.

Tip

To simplify ordered lists and allow for moving items in the list around, use 1. for each item. If a list needs to be broken, numbering is only continued if each entry is labeled using 1., 2., 3., … format.

  • When rendering your document to HTML, callout blocks are interactive and can be collapsed and opened.
