+
+This extension allows you to set up an A/B test with different available Hyvä and the Luma fallback checkout.
+
+It will randomly do a 50% split between the configured Hyva Checkout and the Luma fallback checkout.
+
+## Installation
+
+```bash
+composer require elgentos/magento2-hyva-checkout-ab-test
+bin/magento set:up
+```
+
+## Configuration
+
+None, as of now.
+
+## Reports
+
+You can check the progress of the A/B test by running this query;
+
+```sql
+SET SQL_MODE='';
+SELECT quote.active_checkout_namespace as checkout, COUNT(quote.entity_id) as quotes, COUNT(sales_order.quote_id) as orders, (COUNT(sales_order.quote_id) / COUNT(quote.entity_id)*100) as conversion_percentage
+FROM quote
+         LEFT JOIN sales_order ON quote.entity_id = sales_order.quote_id AND sales_order.state IN ('completed', 'processing')
+WHERE quote.active_checkout_namespace IS NOT NULL
+GROUP BY quote.active_checkout_namespace;
+```
+
+If you want to see the results in the Magento admin, you can install [degdigital/magento2-customreports](https://github.com/degdigital/magento2-customreports) and add the above query. Be sure to leave out the SQL_MODE part (Magento does this for you) and leave no trailing/leading white lines.
