1. Include the SWG CSS and JavaScript files in your HTML:

<!-- If installed via npm -->
<link rel="stylesheet" href="path/to/swg.css" />
<script src="path/to/swg.js"></script>

<!-- Or if using unpkg -->
<link
  rel="stylesheet"
  href="https://unpkg.com/senangwebs-gallery@latest/dist/swg.css"
/>

2. Create your gallery structure using data attributes:

<div data-swg data-swg-page>
  <div data-swg-item data-swg-caption="Beautiful sunset">
    <img src="path/to/image1.jpg" alt="Sunset" />
  </div>
  <div data-swg-item data-swg-caption="Mountain view">

  <div data-swg-item data-swg-caption="Ocean waves">
    <img src="path/to/image3.jpg" alt="Ocean" />
  </div>

The gallery will automatically initialize when the page loads.
