Instagram is a social media platform that allows users to share photos and videos of their lives. To use Instagram, you must first create an account and then sign in. After signing in, you can find the Instagram app on your device. Once you open the app, you will see a list of icons at the top of the screen. The leftmost icon is for your profile picture and the rightmost icon is for your posts. To post a photo or video, just click on one of these icons and then type in a caption. After typing in a caption, you can click on the “post” button to publish your photo or video. If you want to share your photo or video with other people, just click on the “share” button next to each person’s name in the bottom left corner of your screen. After sharing your photo or video with other people, you will need to login again so that they can see it.
