ChargeKeep

Quick domain connection, easy-to-understand instructions (especially the part about connecting to PayPal). I hope to add:
- Added changes theme to the cart on the CRM side (same as ChargeKeep form).
- Make a mini landing page for the CRM domain name, because usually customers will be curious to find the main domain name to see, but when they look at it, they will see errors, and new customers will have a feeling of distrust.
- The footer of the payment page still has the word ChargeKeep, so it should be hidden, replaced, or, if left, need to add an affiliate link (this will be more fair for both parties).
