 Easiest way to start using Ionic Core is by adding a script tag to the CDN:
 
 ```html
-<link href="https://unpkg.com/@ionic/core@4.3.0/css/ionic.bundle.css" rel="stylesheet">
-<script src="https://unpkg.com/@ionic/core@4.3.0/dist/ionic.js"></script>

+<script src="https://unpkg.com/@ionic/core@4.3.1/dist/ionic.js"></script>
 ```
 
 Any Ionic component added to the webpage will automatically load. This includes writing the component tag directly in HTML, or using JavaScript such as `document.createElement('ion-toggle')`.
