It's literally that simple to get remote access to your desktop or laptop from your iPhone or iPad (or other Mac, if you're using the Mac version.)
If you haven't saved or recently entered your password, you'll be asked to enter it for security. On the iPad you can switch to a grid view to easily re-oder them as well. Once you have a screen set up, you'll see it available on the Screens desktop. If you're a more advanced, or security conscious user, you can also add machines via IP address or Hostname, enable SSH tunneling, toggle color-depth, and create custom gestures. You still have to enter your own username and password, either your Mac user account, or VNC account.
