-### Cryptocurrency Payment Gateway Plugin for Gravity Forms by CryptoPay
+### Cryptocurrency Payment Gateway for Gravity Forms by CryptoPay
 
 First of all, we would like to point out that this plugin is not a standalone plugin. This plugin is a **<a href="https://beycanpress.com/cryptopay/?utm_source=wporg_readme&utm_medium=cryptopay_gravity_forms">cryptocurrency payment gateway for Gravity Forms</a>**. In other words, users who want to sell courses with cryptocurrency payments can use WordPress and Gravity Forms. However, this plugin is a plugin for CryptoPay and a cryptocurrency payment gateway for Gravity Forms. So it's actually CryptoPay, which is the main plugin that handles cryptocurrency payments for WordPress. Therefore, users must have both plugins.
