How to create an account ?
You can sign up to an Instagram account either on pc, mac, or smartphone. Go to https://www.instagram.com/ and click “sign up” then fill up the form with your personal details (or log in with your facebook account) and click “sign up” again.
Add your profile photo, connect to facebook to find contacts, and you have now access to Instagram. On the browser version of Instagram, you can't publish pictures but you can follow, like, and comment on post. In order to publish on Instagram, you need to use the windows 10, iOs (on the iOs Store) or Android app (GooglePlay).
