# Checkout alerts

Unlike Shopify Functions, this extension isn't limited by line item quantity and offers better optimization.

* Go to "**Checkout alerts**" menu
* Add block "**Pareto - Limit Checkout**" in checkout page as [guide here](https://docs.paretodeals.com/pareto-limit-purchases/pages/aS4FBglD9AAMv278muN2#id-3.-add-block-in-checkout-page)
* Checked "**Show notification**" option to display an alert when the customer's order does not meet the limit rule.

* Checked "**Show product component**" option to display details of products that do not meet the limit rule. This allows customers to add or remove products to ensure their order complies with the rule.
