Basic instructions for installing tile over cement in garage?

I am looking to install tile over a cement floor in my garage 440 sq ft. It looks like it has a downward slope (maybe since its a garage?) . What would be my basic steps in order to install it right?

Do I need to put self leveler to get rid of the downward slope? If so, do I need to put primer down first?

Do I need the orange membrane ?

Any other tips or pointers would be greatly appreciated! Thanks!
