- Markdown is a lightweight markup language with plain-text-formatting syntax, created in 2004 by John Gruber and Aaron Swartz. Markdown is often used for formatting readme files, for writing messages in online discussion forums, and to create rich text using a plain text editor. Since the initial.
- Here's how to format Markdown cells in Jupyter notebooks: Headings Use the number sign (#) followed by a blank space for notebook titles and section headings: # for titles ## for major headings ### for subheadings #### for 4th level subheadings; Emphasis Use the following code to emphasize text: Bold text: string or.string. Italic text: string or.string.

Quite the same Wikipedia. It follows the same syntax as regular Markdown code blocks, with ways to tell the highlighter what language to use for the code block. The language will be detected automatically, if possible. Or you can specify it on the first line with 3 colons and the language name.

Details
GFM enables the tasklist extension, where an additional processing step isperformed on list items.
A task list item is a list item where the first block in it is a paragraphwhich begins with a task list item marker and at least one whitespacecharacter before any other content.
A task list item marker consists of an optional number of spaces, a leftbracket, either a whitespace character or the letter x
in eitherlowercase or uppercase, and then a right bracket.
When rendered, the task list item marker is replaced with a semantic checkboxelement; in an HTML output, this would be an <input type='checkbox'>
element.
If the character between the brackets is a whitespace character, the checkboxis unchecked. Otherwise, the checkbox is checked.
This spec does not define how the checkbox elements are interacted with: inpractice, implementors are free to render the checkboxes as disabled orinmutable elements, or they may dynamically handle dynamic interactions (i.e.checking, unchecking) in the final rendered document.

Examples
GitHub Flavored Markdown is getting a little Task List flavoring.
Today, we’re shipping an enhancement to our Markdown pipeline to support task lists. Task lists are lists with items marked as either [ ]
or [x]
(incomplete or complete). For example:
This renders as a list of checkboxes. If you can modify the Markdown text, you can check or uncheck the boxes and the text will automatically update.
You can use task lists to break down large issues and discourage the creation of many microscopic issues, allowing you to focus on interacting with the list instead of editing Markdown.
The overriding design goal for Markdown’s formatting syntax is to make it as readable as possible. The idea is that a Markdown-formatted document should be publishable as-is, as plain text, without looking like it’s been marked up with tags or formatting instructions.

Markdown Check Mark
We chose this syntax to stay true to Markdown’s principle of being easy to read in plain text. It is already in common use and appealing without having to be rendered.
Oh, and one more thing:
Markdown To Do List
Issues and pull requests with task list items defined will summarize the task list on the pull request listing and any cross reference.
