Every developer, technical writer, and engineering team eventually faces the same question: should we use Markdown or a rich text editor for our documentation?

The answer, overwhelmingly, has been Markdown. GitHub, GitLab, Stack Overflow, Reddit, Discord, Notion, Obsidian, and countless other platforms have adopted Markdown as their primary text formatting language. But why? What makes Markdown better than traditional rich text editors like Google Docs or Microsoft Word for technical content?

What is Markdown?

Markdown is a lightweight markup language created by John Gruber in 2004. It uses simple text syntax — like # for headings, ** for bold, and - for lists — to define formatting. A Markdown renderer then converts this plain text into HTML for display.

Here’s what Markdown looks like in practice:

# Project Architecture

This module handles **user authentication** using:

- JWT tokens for session management
- OAuth 2.0 for third-party login
- Rate limiting on all endpoints

The same content in a rich text editor would require clicking toolbar buttons, navigating menus, and manually formatting code blocks — all of which are slower and less precise.

Why Developers Choose Markdown

1. Version Control Friendly

This is the single biggest reason developers prefer Markdown. Because Markdown files are plain text, they work perfectly with Git:

  • Meaningful diffs — you can see exactly what changed in a documentation update
  • Merge conflict resolution — text-based merges are straightforward
  • Code review — documentation changes can be reviewed alongside code in pull requests
  • History tracking — full change history with git log

Rich text formats like .docx are binary files. Git can’t show meaningful diffs, merges create unresolvable conflicts, and code review tools can’t display them inline.

2. Lives Alongside Code

Markdown documentation can live in the same repository as the code it describes. This means:

  • README.md at the project root explains what the project does
  • CONTRIBUTING.md guides new contributors
  • docs/ folder contains detailed documentation that’s always in sync with the code
  • Inline documentation — API docs, architecture decisions, and runbooks live where developers already work

With rich text, documentation lives in a separate tool (Confluence, Google Docs, Notion), inevitably falls out of sync with the code, and creates a fragmented knowledge base.

3. Portability and Longevity

Markdown is plain text. It can be opened in any text editor, on any operating system, without any special software. A Markdown file created in 2004 is just as readable today as it was then.

Rich text formats are tied to specific applications. A .docx file requires Microsoft Word (or a compatible viewer). A Google Doc requires a Google account. A Confluence page requires a Jira license. Markdown requires nothing.

4. Speed of Writing

Experienced Markdown users write significantly faster than they would in a rich text editor. There’s no need to reach for the mouse, click formatting buttons, or navigate menus. Everything is done from the keyboard:

  • # Heading instead of selecting text → clicking the heading dropdown → choosing H1
  • **bold** instead of selecting text → pressing Ctrl+B
  • - item instead of clicking the bullet list button
  • ```python instead of inserting a “code block” widget

5. Extensibility

Markdown has evolved far beyond basic formatting. Modern extensions include:

  • GitHub Flavored Markdown (GFM) — tables, task lists, strikethrough, footnotes
  • Mermaid diagrams — flowcharts, sequence diagrams, Gantt charts, ER diagrams
  • KaTeX / MathJax — LaTeX math equations for scientific content
  • Syntax highlighting — language-specific code coloring
  • Front matter — YAML metadata for static site generators

These extensions mean Markdown can handle everything from simple notes to complex technical documentation with diagrams, equations, and interactive elements.

When Rich Text Might Be Better

To be fair, rich text editors excel in certain scenarios:

  • Non-technical audiences — business stakeholders who aren’t comfortable with markup syntax
  • Heavy visual formatting — marketing materials, proposals, and documents with complex layouts
  • Real-time collaboration — Google Docs excels at simultaneous editing (though HackMD and others bring this to Markdown)
  • Embedded media — documents with many images, videos, and embedded content

For these use cases, tools like Google Docs or Notion remain excellent choices. But for technical documentation, the advantages of Markdown are overwhelming.

The Mobile Challenge

Markdown’s one weakness has traditionally been mobile rendering. On a phone, you can’t just “open a .md file” and expect it to render beautifully. Most file managers display raw Markdown syntax, which defeats the purpose.

This is exactly the problem MerMD solves. It’s a dedicated Markdown viewer for Android that renders your files with:

  • Full GitHub Flavored Markdown support
  • Native Mermaid diagram rendering (flowcharts, sequences, Gantt charts, and more)
  • KaTeX math equations for scientific content
  • Syntax highlighting for 20+ programming languages
  • Direct integration with GitHub, GitLab, Google Drive, OneDrive, and Dropbox

With MerMD, you can read Markdown documentation on your phone with the same quality you’d expect on a desktop — making Markdown truly platform-independent.

Getting Started with Markdown

If you’re new to Markdown, here are the essentials:

# Heading 1
## Heading 2
### Heading 3

**bold text**
*italic text*
~~strikethrough~~

- Bullet list item
1. Numbered list item

[Link text](https://example.com)
![Image alt text](image.png)

`inline code`

| Column 1 | Column 2 |
|----------|----------|
| Data     | Data     |

> Blockquote

- [x] Completed task
- [ ] Pending task

It takes about 10 minutes to learn the basics, and most developers become proficient within a week. The syntax is intentionally designed to be readable even without rendering — a Markdown file in a plain text editor still makes sense.

Conclusion

The Markdown vs rich text debate has a clear winner for technical teams. Markdown’s compatibility with version control, its portability, speed of writing, and extensibility make it the standard for modern documentation. From README files to API docs to architectural decision records, Markdown is how the software world communicates.

And with tools like MerMD, the mobile reading experience matches what you’d expect on desktop — with native Mermaid diagrams, math equations, and cloud storage integration built right in.
