Explanation of Licensing procedures
Some products require a license to work. We supply the license in such cases. One license is valid for one domain or subdomain, unless more licenses are purchased.
However, you can use the license on any number of test domains or subdomains.
You can use the supplied license key on localhost without consuming any license.
You can also use the supplied license key on test domain or subdomain without consuming any license. Domain or subdomain is considered test instance if it contains any of the strings test or demo in domain/subdomain name.
Examples: mytest.abc.com or demo2.xyz.com or mydemo.com.
You can use your license on unlimited test domains/subdomains.
