NodeBook provides free online educational content and paid digital products. The current paid product is NodeBook Digital Edition Bundle: The downloadable NodeBook bundle: digital book files, slide decks, cheatsheets, and included updates as the book grows.

The online guide may change as chapters are written, revised, moved, or removed. Paid files may receive updates when updated files are prepared for release.

Paid orders are processed through Polar. Polar acts as merchant of record for paid orders and handles checkout, payment processing, applicable taxes, receipts, and payment-related buyer requests.

Prices shown on this site may be presented before tax. Polar shows the final checkout total before payment. Product access and product support are handled by us.

Paid digital products are delivered as downloadable files or access links after Polar confirms payment. Keep your receipt and download email. Support can help restore access when the purchase can be verified.

The paid product is licensed to the purchaser for personal use. Redistribution, resale, public posting, file sharing, and uploading the paid files to shared repositories or training datasets require written permission.

You may use the free online content for reading, learning, and normal referencing. You may link to public pages.
