Using MapsVTT Help

I'm setting up a new campaign and it's going to be online between friends with me as DM. I'm trying to figure out the best way to run it, and since most already have accounts and characters build here and they're on discord I figured I'd just try to figure out how to use DnDB's Maps. I can't tell what my players are seeing on the map or even how to make it so they would see it. I'm sure a lot of this has to do with coming from pen and paper, but I'm feeling very lost with it all. I've also looked at Roll20 and it doesn't seem any less confusing honestly.  Any help or any direction anyone could point me would be amazing. 

I mentioned this in the other thread where you posted this, but to show the map to the players, click the "Display Map" button.

To view what the players see, click the "Spectator View" button (the icon looks like a computer monitor) and it'll open the player view in a new tab.
