This tutorial guides users on how to add a donation button to a Jamstack site using Stripe, allowing them to accept donations securely. The process involves creating a product on Stripe, obtaining a publishable key, and adding HTML and JavaScript code to display the donation button and handle payments. The tutorial also includes a demo website with test mode functionality, as well as instructions for testing and deploying the site to Netlify or other servers. Once live, users can start accepting real donations by switching their Stripe account to live mode and updating the publishable key. Additional resources are provided for further learning and implementation.
