To add or create a new domain in Plesk Control Panel, you can follow these steps:

Step 1: Log in to your Plesk Control Panel using your username and password.

Step 2: Once logged in, you'll see the Plesk Dashboard. Click on the "Websites & Domains" tab.

Step 3: In the "Websites & Domains" section, click on the "Add Domain" button.

Step 4: On the "Add Domain" page, enter the following information:

Domain name: Enter the domain name you want to add, such as "example.com".

Hosting type: Select the hosting type based on your requirements. You can choose from options like "Website Hosting," "Forwarding," or "No hosting."

Hosting Settings (optional): If you selected "Website Hosting" as the hosting type, you can configure additional settings such as the document root, PHP support, and SSL/TLS certificate.

Step 5: Once you have entered the domain name and made any necessary selections, click on the "OK" button to create the domain.

Step 6: Plesk will now create the domain and update the necessary configurations. You'll see a confirmation message once the domain creation is successful.

Step 7: If you selected "Website Hosting" as the hosting type, you can now upload your website files to the document root directory or use the Plesk File Manager to manage your files.

Step 8: If you need to configure additional settings for the domain, such as email accounts, databases, or subdomains, you can do so by navigating to the domain's overview page and accessing the corresponding sections.

That's it! You have successfully added or created a new domain in Plesk Control Panel. You can now configure and manage the domain settings based on your requirements.
