Markdown Guide: Syntax, Tools, and Best Practices
Learn Markdown syntax for headings, lists, links, code blocks, and tables. Tools for writing, previewing, and converting Markdown to HTML.
Markdown is the lingua franca of technical writing
README files, blog posts, documentation, chat messages, and note apps all use Markdown. It is plain text with lightweight formatting syntax — readable as source, renderable as HTML. Learning Markdown takes 15 minutes and saves hours of HTML typing.
Essential Markdown syntax
Headings: # H1, ## H2, ### H3. Bold: **text**. Italic: *text*. Links: label. Images: !alt. Inline code: `code`. Code blocks: triple backticks with language identifier. Lists: - item or 1. item. Blockquotes: > quote.
Advanced syntax
Tables: | Header | Header | with --- separator rows
Task lists: - [ ] unchecked, - [x] checked
Strikethrough: ~~text~~ (GitHub Flavored Markdown)
Horizontal rules: --- on its own line
Nested lists: indent with 2 or 4 spaces
Footnotes: [^1] reference syntax (platform-dependent)
Preview Markdown live
The Markdown preview tool on Zovaty renders Markdown as HTML in real time. Type on the left, see output on the right. Use it to verify formatting before publishing to GitHub, Notion, or your CMS.
Converting between Markdown and HTML
Need to convert HTML back to Markdown? Use HTML to markdown. Need to format existing Markdown? Use the Markdown formatter for consistent spacing and structure.
Markdown best practices
One H1 per document (usually the title)
Use ATX headings (#) rather than underline style
Specify language on code blocks for syntax highlighting
Use reference-style links for documents with many URLs
Keep lines under 80 characters for readable diffs in git
Add alt text to every image for accessibility
Conclusion
Markdown is essential for developers, writers, and anyone publishing technical content. Learn the basics, preview with Zovaty tools, and write in plain text that renders everywhere.
Markdown across platforms
GitHub, Notion, Slack, Discord, and most CMS platforms support Markdown with platform-specific extensions. GitHub adds task lists and tables. Notion uses a different block-based editor that imports Markdown imperfectly. Test rendering on your target platform before publishing.
Markdown for documentation sites
Static site generators (Hugo, Jekyll, Docusaurus, MkDocs) use Markdown as the primary content format. Organize docs with folder structure mirroring navigation. Use front matter (YAML metadata) for titles, descriptions, and ordering.
Collaborative writing in Markdown
Markdown files diff cleanly in git — changes are visible line by line. This makes Markdown ideal for team documentation stored in repositories. Use pull requests for doc review the same way you review code.
Markdown linting and consistency
Markdownlint and similar tools enforce consistent heading hierarchy, list formatting, and link style across team documentation. Configure rules in your repository and run in CI to catch formatting issues before merge.
Exporting Markdown to other formats
Pandoc converts Markdown to PDF, DOCX, HTML, and LaTeX. Use for generating client deliverables from internal Markdown docs. The HTML to markdown tool works in reverse for importing web content into your documentation system.
Markdown templates for common documents
Create templates for meeting notes, RFCs, bug reports, and README files. Templates ensure consistent structure and reduce blank-page friction for team documentation.
Math and diagrams in Markdown
KaTeX and MathJax render mathematical notation in Markdown on supported platforms. Mermaid diagrams render flowcharts and sequence diagrams from text syntax. GitHub supports both natively.
Markdown for static site generators
Front matter in Markdown files configures title, date, tags, and layout. Hugo, Jekyll, Astro, and Next.js all consume Markdown with YAML front matter. Learn your generator's conventions for optimal workflow.
Driving Markdown adoption in teams
Start with README files and meeting notes — low-stakes documents where Markdown's simplicity shines. Expand to RFCs, design docs, and runbooks as comfort grows. Provide a team cheat sheet with common syntax.
Summary: Markdown essentials
Learn core syntax in 15 minutes. Preview with markdown preview. Use for docs, READMEs, and blog drafts. Adopt team-wide for git-friendly documentation.
Frequently asked questions
Is Markdown the same everywhere?
Core syntax is universal. Extensions like tables, task lists, and strikethrough vary by platform (GitHub, CommonMark, etc.).
Can I use HTML inside Markdown?
Most parsers allow inline HTML. Block-level HTML may break Markdown parsing in some renderers.
What is GitHub Flavored Markdown?
GitHub's Markdown extension adding tables, task lists, strikethrough, and autolinks.
How do I add syntax highlighting to code blocks?
Add the language name after the opening triple backticks: ```javascript
Can I use Markdown in emails?
Some email clients render basic Markdown. For reliable formatting, convert to HTML first using a Markdown processor.
