Congratulations your hosting account is now live.
Delete this page (index.html), or replace it by unlocking FTP in your hosting control panel and uploading your own.
Upload all files which you want viewed publicly to the public_html folder.
NOTE: If you only have a 'Parked Domain Control Panel' package you will need to upgrade it to a hosting account to upload web pages/files/a web site etc.
HOW DO I UPGRADE MY ACCOUNT?
