You CAN add our site, or any site that matter, to the homescreen of your iOS device.
1) Open up Safari on your device and browse to our site at http://mghs-mononagrove.libguides.com.
2) Tap the action button in the top right corner of your screen (box with an arrow pointing up). One of your options will be to "Add to Home Screen."
3) Enter the name you'd like to appear below the icon on your screen. We suggest MGHS Library because it'll fit without cutting off.
