# Market App

Imagine you run a clothing store online shop. You would love a screen that displays the products you registered in the content studio in an attractive way, but building one yourself every time is a burden. The reverse can also be true: sometimes you want to let other people use a screen you built well in their own workspace.

This group covers the flow of **building an app and putting it on the market, then picking one from the market and bringing it into your own *Space* (the workspace that holds your content, members, and settings) to use**. The apps exchanged this way are called *Market App*s, and the market where apps are displayed is called the marketplace in the content studio. Putting an app out (publishing) happens at the company-wide (organization) level, while bringing one in to use (installing) happens at the *Space* level.
