STEPS TO GETTING APOLLO/QUERY DATA TO SHOW????

I have several queries made, I’m trying to show the information in my app. What components need the Apollo tag around them? ALSO, is it just one file that will be the setup to get the data? I know of the query setup layout you do, BUT, it’s not showing data.

What’s a simple tutorial?

ALSO.... do I set the client={client} do I set the url to my localhost????
