Once in the Instagram app, you will see an icon of a clapperboard in the menu at the bottom of your screen. Tapping on this icon will take you to the Reels section of the Instagram app. You will be shown Reels based on the people you follow and the content you usually interact with on Instagram.

Open Instagram and tap the plus (+) icon at the bottom of the screen to create a new post. To make that post a Reel, use the bar at the bottom to scroll over to the Reels tab. Choose one or multiple photos or videos from your device's camera roll, and use the sliders at the bottom of the screen to trim their length.
