Deep or Dynamic Link Help

Hi Everyone,

Good day to all of you!

I would like to ask for help. I’ve been searching the internet but I can’t see a step by step tutorial on how to do Deep Link of Dynamic Link.

Whenever I post a link in facebook it will open facebook’s browser but I want it to open the app or go to the app store instead if the app isn’t install yet.

I hope someone who can give me a step by step on how to do this.

By the way I have zero experience coding. Badly need help.

Thank you!
