Instagram’s new Favourites feed is a nice way to stay up to date with your friends and favorite users activity. But for that, you have to maintain a list of Favourites.
Basically, all you need to do is add people to your Favourites, witch is not very different from following someone on Facebook.
You need to open someone’s profile on Instagram and then tap the Following button.
This opens up a small menu in the lower part of the screen. Here you need to hit the “Add to Favourites” option.
To manage the Favourites list you need to go to your own profile page and open the right side menu where you’ll see the Favourites option among others.
This is where you can remove or ad other favourites, or just search for someone in this list.
