# Upgrade from Editor v2 to Editor v3

Upgrading your Topol Plugin from Editor 2 to Editor 3 is a smooth process that usually takes about 5 minutes. There are no major changes that break your existing templates or functionality, so it’s a straightforward update.

## What Do You Need to Change?

You only need to update the script that loads the editor in your HTML.

Change this line:

```html
<script
  src="https://d5aoblv5p04cg.cloudfront.net/editor-2/loader/build.js"
  type="text/javascript"
></script>
```

to:

```html
<script
  src="https://d5aoblv5p04cg.cloudfront.net/editor-3/loader/build.js"
  type="text/javascript"
></script>
```

That’s it!
