Trello uses the revised Markdown syntax, a simple language for formatting text. Markdown allows you to format text in Trello’s bio section, card description, checklists, and comments.
Note that not all markdown syntaxes work across all sections of a Trello card. For instance, you can use markdown to bold text in the comments section. However, you can’t format text as an H1 or H2 with a markdown in the comments. You also can’t use Markdown syntax at all on the card titles.
You can also use keyboard shortcuts to format text in various places in Trello.
This article will give you the keyboard shortcuts and markdown syntaxes you can use on Trello for formatting text and the sections you can use those syntaxes in.

If you want to start a list with a specific number, use a backslash to restrict markdown from formatting the text as an ordered list:
How To Create Nested Lists on Trello
You can also create nested lists (a list within a list) by leaving a blank space before the number or the hyphen like this:
