To install WHMCS please follow the Docs.
Currently, we do not offer a white-label WHMCS license reseller system. Our development team is working on it, and it will be available soon. Until then, you can share the same License.php file with your customers using our download link or host the file on your own website.
Note: The white-label reselling is not supported at this time. When reselling our WHMCS licenses, you must use our brand.
