# Install Nightfall DLP for Zendesk
### First-time setup: Adding your first Zendesk instance
1\. Click **Begin Setup** to start the simple installation flow via Nightfall
2. Nightfall for Zendesk supports both sandbox and production instances. Please select the one applicable to your setup. In this example, we will be onboarding a production instance.
3. Click **Continue** once you select your instance type.
4. Type in your Zendesk subdomain or Instance name in the text field. In this example, we added *nightfall3968.* Select **Connect to Zendesk** when completed. This will navigate to the Zendesk sign-in page where we recommend the service account with full admin privileges is used.
5. Select **Switch to agent sign-in** (if applicable), then proceed to add the email and password associated with either a service account (*Recommended)* or a user account that has full Zendesk admin privileges.
6. You will be navigated to an authentication page with more information on how Nightfall and Zendesk will establish a secure connection. Please click **Allow** to continue
7. Once you select **Allow,** you will be navigated back to Nightfall and be prompted to install the Nightfall DLP Zendesk Marketplace app.
* ***Note**: Authentication and App installation for Zendesk are two independent steps. Both need to be completed for the setup to be complete.*
8. If you have already installed the app via the Zendesk Marketplace, you can go directly to Step 9. Click **Install**. In a new tab, you will be prompted to install the Nightfall DLP Zendesk marketplace app via the Zendesk Admin console.
* Optional: Add Role or Group restrictions which will limit who can remove or add the applications from Zendesk.
9. Congratulations :tada: You now have a fully set up instance of Zendesk connected with Nightfall!
11. In Settings, ensure the **Status** and **App Installed** are '**Authorized**' and **'Yes'** with a green highlight. If a Zendesk instance becomes disconnected, you can use this settings page to monitor and reconfigure any connections as needed.
### Adding additional Zendesk instances
12. If you would like to add another instance of Zendesk, Click **+ Add Instance** and repeat steps 1-10 above.
