You made it!
That's all there is to creating PDF documents in PDFKit. It's really quite simple to create beautiful multi-page printable documents using Node.js!
This guide was generated from Markdown files using a PDFKit generation script. The examples are actually run to generate the output shown inline. The script generates both the website and the PDF guide, and can be found on Github. Check it out if you want to see an example of a slightly more complicated renderer using a parser for Markdown and a syntax highlighter.
If you have any questions about what you've learned in this guide, please don't hesitate to ask the author or post an issue on Github. Enjoy!
