Usage guide

Draft Markdown and verify the rendered structure before publishing

Markdown is easy to type but subtle formatting mistakes can change headings, lists, links, code blocks, and tables. A live preview lets you check both the source and the rendered result while keeping the writing workflow lightweight.

How to use Markdown Editor

  1. 1.Write or paste Markdown into the source editor using clear heading levels and consistent list indentation.
  2. 2.Compare the preview with the source, paying special attention to nested lists, links, code fences, and tables.
  3. 3.Copy the final Markdown or rendered result into the destination system and verify that its Markdown flavor behaves the same way.

Examples

  • Use fenced code blocks for multi-line source code rather than indenting arbitrary text.
  • Check a README table in the preview before committing it to a repository.
  • Verify relative and absolute links before publishing documentation.

Limitations and notes

  • Different platforms support different Markdown extensions, so a preview cannot guarantee identical rendering everywhere.
  • Do not paste secrets, API keys, or private credentials into documentation drafts that may later be shared.

Why does Markdown look different on GitHub and another site?

Platforms can use different Markdown flavors and extensions for tables, task lists, HTML, footnotes, and line breaks.

Can I include raw HTML in Markdown?

Some renderers allow it and others sanitize or block it. Check the rules of the destination where the Markdown will be published.
