markdown-syntax-fundamentals

Markdown syntax uses simple conventions: # for headings, *text* for emphasis, [link](url) for links, and triple backticks for code blocks. These core elements structure README files, wikis, and project documentation in a readable, version-control-friendly format.

Use fenced code blocks with triple backticks and a language identifier (```python, ```javascript) for syntax highlighting, or inline backticks for single expressions. This approach works across GitHub, CommonMark renderers, and most documentation platforms.

Ordered lists use 1., 2., etc.; unordered lists use -, *, or +. Links follow [text](url) syntax; images use . Reference-style links separate definitions for cleaner source files, and task lists use - [ ] checkboxes for tracking.

Use semantic heading hierarchy (# for main, ## for subsections), descriptive link text instead of "click here", alt text for images, and blockquotes for callouts. These practices align with CommonMark and GitHub Flavored Markdown standards for maintainable documentation.

Yes. Markdown core syntax works universally across GitHub, GitLab, documentation sites, and knowledge bases. GitHub Flavored Markdown adds task lists and tables; CommonMark ensures portability. Check platform-specific extensions for advanced features like strikethrough or footnotes.

Backslash (\) escapes special characters like #, *, and [. For line breaks, use two trailing spaces or a blank line between paragraphs. These techniques prevent formatting conflicts and maintain source readability.
