Instagram is a social media platform that allows users to share photos and videos. It was created in 2010 by Kevin Systrom and Mike Krieger. The app has over 1 billion active users, making it one of the most popular social media platforms. There are a few ways to know if you’ve joined Instagram: if you have an iPhone or Android device, the app will automatically download when you open the App Store or Google Play Store; if not, you can download it from Instagram’s website. Once installed, sign in with your username and password. If you don’t have an account, sign up for free at Instagram.com. Once you have an account, follow these steps to join: open the app and tap on the three lines in the top left corner (this will open up your profile); next to “Following” tap on “Add People”; scroll down until you see “Instagram”; type in your username (this is what will show up on other people’s profiles); hit “Follow”; and finally hit “Done”. ..
