Frequently Asked Questions

Markdown is a lightweight markup language that uses simple symbols to format plain text. Created by John Gruber in 2004, it is characterized as being easy to read and write. It is widely used in GitHub, GitLab, and various blogging platforms.

GFM is a markdown specification extended by GitHub, adding features such as tables, checklists (Task Lists), strikethroughs, automatic links, and code block language specification to standard Markdown. This is especially useful for writing developer documentation.

Add the language name immediately after the opening triple backticks (```). For example, start with ```javascript to apply JavaScript syntax highlighting. Many languages are supported, including Python, TypeScript, and CSS.

Although there is no direct URL sharing function, you can download your written content as an .md file or copy the rendered HTML and share it via email, messenger, etc. Upload it to your GitHub repository and it will be automatically rendered.

No. All Markdown editing and rendering is handled client-side within the browser. The information you enter is not sent to the server, so you can write personal information or sensitive documents with confidence.

Tips & Best Practices

  • When writing your README.md, you can preview it with this tool to see the rendering results before uploading it to GitHub.
  • Create tables with the pipe character (|) and hyphens (-), and use colons (:) to specify column alignment.
  • When inserting an image, use the ![alternative text](URL) syntax, and you can use the web image URL directly.
  • Checklists are useful for project management because you can create a to-do list with - [ ] and - [x].
  • Markdown grammar can be displayed without escaping within a code block, making it suitable for writing grammar explanation documents.
