If I may...
Quickstart include Joomla inside, and that needs database. This same would be for Drupal and Wordpress.
If you don't have access to create a new database but you have access to files (!) you can use this trick:
- Install Joomla via cPanel (hosting platform) do all steps - after you should see demo joomla site.
- Then use File manager and edit file configuration.php - copy content from it to your notepad
- Later you need to use from it host name, user name, database name and password.
- Delete all folders and files from preinstalled Joomla (from step 1)
- Upload all files from our joomshaper quickstart (unzip before, if you cannot unzip on server)
- Run installer - follow all step
- Use Database access (from 3)
If you don't have access to File Manager - ask hosting support (!)
