Markdown is a plain text format for writing documents, offering an good balance of readability, simplicity, and functionality for creating structured content on its own. In KF it is used in the 'text' field of each item, while the item is being edited. Later is rendered as HTML.

This document describes the Markdown variant that KF implements. It has some differences with respect to Commonmark.

The following items differ:

• Title
• Tables
• Math

Title

#! Title

Headers

Headers start with one or more (up to 6) '#', followed by a space and text, up to the end of the line. Numbered headers are not supported.

An optional reference in the form {#ref} can be added before the end of line. This reference will be the ID attribute of the header an can later be used to access document parts.

Headers

# Chapter 1 {#chapter1} {!type}

{#token} substitutes the normalized header. {!type} states the type of this section, and is used in document comparisons.
