What is the Documentation Generator?

The Documentation Generator is a client-side Markdown editor and renderer designed to help developers write, format, and preview technical documentation. By compiling Markdown files into styled HTML sheets, you can draft readmes, api specs, and developer manuals in your browser.

This editor manages all text parsing and preview compiling locally on your machine. Since no text strings, source schemas, or document files are uploaded to external databases, your software guides and project specifications remain completely confidential.

How to Use the Documentation Generator

  1. Input Your Markdown: Type or paste your Markdown syntax directly into the editor pane on the left side.
  2. Observe the Live Preview: The right panel renders your headers, bold text, lists, and code blocks in styled HTML dynamically.
  3. Count Your Words: Click the "Word Count" button to check the word metric for your active document.
  4. Export Your Work: Click the "Export HTML" button to download a styled HTML document directly to your device.
  5. Reset the Editor: Click "Reset" to clear the text area and reload the default documentation template.
