Softaculous is a script installer built into many hosting control panels, including cPanel, DirectAdmin, Plesk and InterWorx. It lists Jamroom in its Portals/CMS category and installs it for you: no download, upload or database to create.
The screens differ a little between hosting providers. The steps are:
https:// if your domain has an SSL certificate.Softaculous creates the admin account for you, so you don't need the Create Admin Account step. Log in to your new site with the user name and password you entered in Softaculous.
Softaculous installs the Jamroom Open Source release it has on file, which may be a little behind the newest release. Update it from the Marketplace (see Your jamroom.net Account and the Marketplace).
Then run the System Check, described in Create the Admin Account, and continue with First Steps after Installation.
