## Exercise: Installing and Using Apps from the Marketplace

In this module we are going to install two apps from the Marketplace that support developers using Contentstack.

1.  Developer Tools

2.  Content Type Visualizer

## **Installing Developer Tools**

Developer tools allow the developer to view the Entry JSON before it is published.  This is very helpful when building apps and looking for the structure and properties of the content type.

1.  Go to the [Marketplace dashboard](https://app.contentstack.com/#!/marketplace/apps)  ([EU Marketplace Dashboard](https://eu-app.contentstack.com/#!/marketplace/apps))

2.  Select Developer Tools, Install App, and choose the Stack of where to install it

## **Installing the Content Type Visualizer**

The Content Type Visualizer is another developer-friendly extension that shows the relationships between Content Types.  It is installed on the Dashboard using the Marketplace.

1.  Go to the [Marketplace dashboard](https://app.contentstack.com/#!/marketplace/apps)  ([EU Marketplace Dashboard](https://eu-app.contentstack.com/#!/marketplace/apps))

2.  Select Content Type Visualizer, Install App, and choose the Stack of where to install it

- Capture one concrete artifact (screenshot, Postman call, or code snippet) that proves the step works in your environment.
- Re-read the delivery versus management boundary for anything you changed in the entry model.
