+# About This Example
+
+This Jekyll site demonstrates how to integrate Buttondown email subscriptions into a static website.
+
+## What is Jekyll?
+
+Jekyll is a simple, blog-aware, static site generator perfect for personal, project, or organization sites. It takes text written in your favorite markup language and uses layouts to create a static website.
+
+## What is Buttondown?
+
+Buttondown is a small, elegant tool for producing newsletters. It's simple, reliable, and privacy-focused.
+
+## How It Works
+
+1. Jekyll generates static HTML pages from your Markdown content
+2. The newsletter form is embedded in the layout template
+3. Form submissions are handled client-side with JavaScript
+4. Subscriptions are processed through Buttondown's API
+
+## Customization
+
+You can customize this example by:
+- Modifying the layout in `_layouts/default.html`
+- Updating styles in the layout file
+- Changing the site configuration in `_config.yml`
+- Adding your own posts in the `_posts` directory
+
+Remember to replace `{username}` with your actual Buttondown username in the configuration file!
