How to create a timeline with publications similar to Facebook

Hi guys! I am creating an application and I have a tight deadline for April 19th. I want to create a timeline with publications, but open to everyone, I want all users to have access and be able to publish something there. I know you need the list viewer and firebase, but I’m not really aware of that. I do not know how to do. Can you help me?
