Now that I have an app set up, how do people install it?
You probably know this already if you’ve ever installed an app, but the general case is that all installation roads lead to your About Page. It’s worth noting that this used to be more true when you had to install an app before you could see any of its content, but it has become slightly less the case now that pages inside an app can be publicly visible.

In Figure 3-7, you’ll note the big blue “Go to Application” button in the top-right, as well as the absence of the links that would enable me to edit the app’s settings (which are present in Figure 3-6).
