Colitisin Markdown: An Introduction

Colitisin Markdown is a lightweight and extensible markup language designed for writing and structuring text content. It is based on the popular Markdown syntax but introduces several enhancements and additional features to improve the readability, maintainability, and extensibility of technical documentation.

Origins and Motivation

Markdown was originally developed by John Gruber in 2004 as a simple way to create formatted text using plain text syntax. Its popularity grew rapidly due to its ease of use, flexibility, and wide adoption by blogging platforms and documentation tools. However, as Markdown became more widely used for writing complex technical documentation, it became apparent that certain limitations and missing features hindered its effectiveness for this purpose.

Colitisin Markdown was created to address these shortcomings by introducing a number of extensions and enhancements to the original Markdown syntax. These extensions provide additional functionality such as improved code formatting, table support, and more flexible heading styles.

Key Features

The core features of Colitisin Markdown include:

  • Syntax highlighting for code blocks: Code blocks can be easily highlighted using a variety of predefined syntax themes, making it easy to share and read code snippets.
  • Table support: Tables can be created using a simple syntax, providing a convenient way to organize and present tabular data.
  • Flexible heading styles: Headings can be formatted using a variety of styles, including underlined, overlined, and double-struck. This allows for more expressive and visually appealing heading structures.
  • Extensibility: Colitisin Markdown is designed to be extensible, allowing users to create custom extensions and plugins to add new functionality.

Syntax Overview

The syntax of Colitisin Markdown is similar to that of Markdown, with some key additions and modifications:


# This is a level 1 heading
## This is a level 2 heading
### This is a level 3 heading

Code Blocks:

function my_function() { console.log(“Hello, world!”); }


| Header 1 | Header 2 | Header 3 |
| Cell 1 | Cell 2 | Cell 3 |
| Cell 4 | Cell 5 | Cell 6 |


Extensions are added using the {% and %} delimiters. For example, the following extension adds a new warning block type:

{% extension warning %}
This is a warning block.
{% end %}

Benefits of Using Colitisin Markdown

Colitisin Markdown offers several benefits for writing technical documentation:

  • Improved readability: The enhanced syntax and features of Colitisin Markdown make it easier to read and understand complex technical content.
  • Increased maintainability: The use of structured headings, code formatting, and tables improves the maintainability and organization of documentation over time.
  • Extensibility: The extensibility of Colitisin Markdown allows users to customize the language to meet their specific needs and workflows.
  • Compatibility: Colitisin Markdown is fully compatible with Markdown, making it easy to transition existing documentation to the new language.

Case Studies

Colitisin Markdown has been successfully used in a variety of projects and documentation efforts:

  • Software documentation: Colitisin Markdown is used to write and maintain the documentation for a number of open-source software projects, including the Fluent UI design system and the RxJS library.
  • Technical white papers: Colitisin Markdown has been used to create technical white papers and articles for a variety of audiences, including developers, engineers, and researchers.
  • Educational materials: Colitisin Markdown is also used to create educational materials, such as tutorials and guides, for students and professionals.


Colitisin Markdown is a powerful and versatile markup language that addresses the limitations of traditional Markdown for writing complex technical documentation. Its enhanced syntax, table support, flexible heading styles, and extensibility make it a valuable tool for technical writers and documentation engineers. As the demand for well-written and maintainable technical documentation continues to grow, Colitisin Markdown is well-positioned to become a leading choice for creating and sharing technical content.
