Here’s a few telltale signs that fall is upon us: Leaves are changing colors, pumpkin-flavored everything lines shelves, and a new OS release from Apple hits today.

The company’s most recent mobile OS release, iOS 9, is here, so VentureBeat put together a quick and easy guide to getting you set up and ready to go.

  1. Back up your precious data using iCloud or a third-party service. Seriously. You don’t want to lose all of those photos or songs, do you?
  2. Make sure your device is compatible with iOS 9. You’ll need an iPhone 4s and later, iPod Touch 5th generation and later, iPad 2 and later, or iPad Mini and later. Check the specifics at the bottom of Apple’s page on what’s new in iOS 9.
  3. Check your available space. You’ll need only a little bit of room on your phone this year — about 1.3GB — for the update. By comparison, iOS 8 is 4.56GB.
  4. Download that sucker. On your iPhone or iPad, go to Settings, then General, and then click on Software Update. You can also use iTunes, if you’d prefer.
  5. Be patient. Apple fanatics are all going to be waiting to get their fingers on the new software as soon as they possibly can, so the download may be a little slow.
