To get started with Alpine.js, you need to include the Alpine.js library in your HTML file. The easiest way is to use a Content Delivery Network (CDN), which lets you quickly add Alpine.js without downloading any files.

Start by opening your HTML file. The recommended practice is to place the script tag for Alpine.js right before the closing </body> tag. This ensures that your HTML content loads first, making your page render faster and preventing potential issues with elements not being available when Alpine.js initializes.

Here is a step-by-step guide:

1. Open your HTML file in a code editor;
2. Scroll to the bottom of the file, just before the closing </body> tag;
3. Add the script tag for Alpine.js using the CDN link;
4. Save the file and open it in your browser;
5. Add a simple Alpine-powered element to confirm Alpine is working.

By following these steps, you will have Alpine.js ready to use in your project. Next, try out a minimal example to see Alpine.js in action.
