To connect your Namecheap domain to your Shopify store, you will need to follow these steps:
Log in to your Shopify account and go to the Online Store > Domains section.
Click on the "Connect existing domain" button.
Enter your domain name and click on the "Next" button.
In the next screen, select the option "Connect domain with third-party DNS" and click on the "Verify connection" button.
You will now see a list of DNS records that you need to add to your Namecheap account. Keep this page open as you will need this information in the next steps.
Log in to your Namecheap account and go to the Domain List section.
Click on the "Manage" button next to the domain name you want to connect to Shopify.
Scroll down to the "Nameservers" section and select the "Custom DNS" option.
In the "Custom DNS" section, enter the DNS records provided by Shopify in step 5.
Save your changes and wait for them to propagate (it can take up to 48 hours for the changes to take effect).
Once the DNS changes have propagated, your Namecheap domain should be connected to your Shopify store. You can confirm this by going back to the Online Store > Domains section in Shopify and checking that the domain status is "Connected".
