# Installation Guide

As a Shopify Plus store, you must enable your `checkout.liquid` layout before installing Vigilance. Request `checkout.liquid` to be enabled from Shopify support [here](https://help.shopify.com/en/questions#/contact). Usually, Shopify resolves this in real time over chat.

If `checkout.liquid` is already enabled, skip this step.

### Add checkout.liquid to your theme

If access to `checkout.liquid` has been enabled, then you can follow the steps below to add the layout to your theme through the code editor in the Shopify admin:

**1.)** From your Shopify admin, go to Online Store > Themes.

**2.)** Find the theme you want to edit, and then click Actions > Edit code.

You should now see `checkout.liquid` listed in the Layout directory.

### Add the Vigilance javaScript snippet to your checkout.liquid

You can add the `checkout.liquid` layout to your theme code by following these steps:

1.) From your Vigilance settings page, copy the provided snippet
