How to open an .md file

A file ending in .md is usually a Markdown document.

Markdown files contain plain text with lightweight formatting symbols. They are commonly used for software documentation, README files, notes, technical specifications, and content written for websites.

Because Markdown is plain text, you can open an .md file with almost any text editor. To see the formatted version, use a Markdown viewer or preview tool.

Is an .md file safe?
