# Discovery

**NDI Discovery** is a tool that enables you set up and manage Discovery Servers within workflows. We cover the capabilities of [Discovery Service](https://docs.ndi.video/all/getting-started/white-paper/discovery-and-registration/discovery-server) in depth in our [White Paper](https://docs.ndi.video/all/getting-started/white-paper).

## **Accessing NDI Discovery**

[Install NDI Tools](https://docs.ndi.video/all/using-ndi/ndi-tools/installing-ndi-tools). After installing it, access NDI Discovery from the [NDI Launcher](https://docs.ndi.video/all/using-ndi/ndi-tools/ndi-tools-launcher) or your applications folder.

Once you've installed Discovery check out our [Getting Started with Discovery](https://docs.ndi.video/all/using-ndi/ndi-tools/ndi-tools-for-windows/broken-reference) guide. For  high level introduction on how Discovery works read [this guide](https://docs.ndi.video/all/developing-with-ndi/developer-guides/receiver-discoverability-monitoring-and-control-overview) on Receiver Discoverability, Monitoring, and Control.

## **Senders**

Displays all NDI sources (“senders”) that have registered with the Discovery Server. Each sender entry shows its device name/hostname, the network address, and port it is streaming from.  Devices appear grouped by hostname. This tab helps you quickly see which NDI devices are currently available to provide streams on your network.

As of **NDI 6.3**, this view also includes senders registered using the new NDI Sender Advertiser APIs. These APIs extend discovery support to senders, coexist with the legacy advertisement system, and enable improved visibility into sender properties and events when used with the Discovery Server.

## **Receivers**

Shows all NDI receivers (endpoints listening for NDI streams) recognized by the Discovery Server. Devices are also grouped by hostname under receivers. This is especially useful when troubleshooting or confirming which machines are actively listening for NDI streams.

From the dropdown carrot under **Receivers** you can specify the source for that receiver

## **Settings**

You can configure or change the Discovery Server IP and port. You can also see whether the application is connected to a Discovery Server and at which IP/port.

For first time set up, when using with [Studio Monitor](https://docs.ndi.video/all/using-ndi/ndi-tools/ndi-tools-for-windows/studio-monitor) for the first time be sure to select the **Allow Receiver Advertising** and **Allow Receiver Control** from the settings
