How to Read GitHub README Files on Your Phone

GitHub’s mobile website renders Markdown README files reasonably well, but it has significant limitations. Code blocks lack syntax highlighting, Mermaid diagrams don’t render, and the reading experience on small screens is far from ideal. If you frequently browse GitHub repositories on your phone — whether for code reviews, open source contributions, or learning — there’s a much better way.

In this guide, you’ll learn how to use MerMD to browse and render GitHub README files with full formatting, syntax highlighting, and Mermaid diagram support on your Android device.

The Problem with GitHub’s Mobile View

When you open a GitHub repository on your phone’s browser, the README renders with basic formatting. But several things are missing or broken:

• No Mermaid diagram rendering — you see raw code blocks instead of visual diagrams
• Limited syntax highlighting — code blocks may lack proper coloring on mobile browsers
• Poor readability — small fonts, awkward horizontal scrolling for code, and no customization
• No offline access — you need an internet connection every time
• No dark mode control — relies on GitHub’s theme settings, not your preference

For developers and open source contributors who spend significant time reading documentation, these limitations add up quickly.

Step 1: Connect Your GitHub Account

After installing MerMD from Google Play, open the navigation drawer and tap GitHub. You’ll be prompted to sign in with your GitHub account using secure OAuth authentication.

Once connected, MerMD gives you full access to:

• Your repositories — both public and private
• Organizations you belong to
• Starred repositories — quick access to projects you follow
• Any public repository — browse by URL or search

Step 2: Browse Repository Files

Navigate through repository directories just like you would on GitHub’s website. MerMD shows you the file tree, and you can open any .md, .mdx, or .markdown file with a single tap.

The file browser supports:

• Branch switching — view documentation from any branch
• Directory navigation — browse nested folders like /docs, /wiki
• File size indicators — see file sizes before opening

Step 3: Read with Full Rendering

When you open a Markdown file, MerMD renders it with everything GitHub supports — and more:

GitHub Flavored Markdown (GFM)

• Tables with column alignment
• Task lists with checkboxes
• Strikethrough text
• Autolinked URLs
• Footnotes and abbreviations

Syntax Highlighting

Code blocks are rendered with proper syntax highlighting for 20+ programming languages including Python, JavaScript, Kotlin, Rust, Go, C++, TypeScript, Java, Swift, and more. You can choose from multiple color themes like Monokai, GitHub, and Dracula.

Mermaid Diagrams

Unlike GitHub’s mobile browser, MerMD renders all Mermaid diagram types natively — flowcharts, sequence diagrams, class diagrams, Gantt charts, ER diagrams, pie charts, and state diagrams. This is critical for repositories that use Mermaid for architecture documentation.

KaTeX Math Equations

Scientific repositories, academic projects, and algorithm documentation often contain LaTeX math expressions. MerMD renders them beautifully with KaTeX, supporting both inline equations and display math blocks.

Beyond GitHub: Other Cloud Sources

MerMD doesn’t stop at GitHub. You can also browse and render Markdown files from:

• GitLab — access projects, groups, and wikis
• Google Drive — open .md files stored in your Drive
• OneDrive — Microsoft cloud storage integration
• Dropbox — access shared folders and documents
• Local storage — open any file from your device

All sources render with the same high-quality engine — Mermaid diagrams, math equations, syntax highlighting, and GFM support work identically regardless of where the file comes from.

Customizing Your Reading Experience

Unlike GitHub’s mobile view, MerMD gives you full control over how documentation looks:

• Light, dark, and auto themes — match your system preference
• Adjustable font size — perfect for reading on tablets or small phones
• Multiple font families — choose the typeface that’s easiest on your eyes
• Code theme selection — Monokai, GitHub, Dracula, and more
• Reading width — control line length for comfortable reading

Export and Share

Found a README you want to share with your team? MerMD lets you export any rendered document as:

• PDF — perfect for sharing via email or Slack
• HTML — self-contained web page with all styles
• High-resolution image — great for presentations and documentation

Conclusion

Reading GitHub README files on your phone doesn’t have to mean squinting at poorly rendered code blocks and missing diagrams. MerMD gives you a native, customizable reading experience with full Mermaid support, syntax highlighting, and direct GitHub integration — all for free.

Whether you’re reviewing pull requests on the train, reading API documentation at lunch, or browsing open source projects from your couch, MerMD makes it effortless.
