About Markdown Previewer
Write Markdown and preview the rendered result. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Review the rendered document, not just the punctuation
Markdown is easy to write but small syntax mistakes can change structure. A live preview makes broken heading levels, list indentation, links and code fences visible before you publish.
Read the preview once as a reader after you finish fixing syntax. Good Markdown still needs clear organization and useful wording.
A realistic example
Before committing a README, preview headings, links, nested lists and fenced code blocks, then click important relative links in the repository context.
When this tool is not the right fit
A Markdown preview does not guarantee that every publishing platform renders extensions in exactly the same way.
