# Install the Advertisement Legacy package in Unity

> Install the Advertisement Legacy package in Unity to enable ad monetization and connect your project to the Unity Ads Monetization dashboard.

> **Note:**
>
> Starting April 1, 2026, apps that monetize with Unity Ads through direct integration through the Advertisement Legacy Package might see reduced ad performance. To avoid reduction in performance, switch to integrating Unity Ads as a bidder.
>
> The Unity Ads network will continue to support and provide fill for all apps using direct integration. However, to maximize revenue and performance, the recommended best practice is to [install the Ads Mediation package for LevelPlay](/grow/levelplay/sdk/unity/package-integration.md.md), Unity's ad mediation platform.

To ensure that you're using the latest version of Unity Ads, we recommend that you install the Advertisement Legacy package from the Unity Editor [Package Manager](https://docs.unity3d.com/Manual/upm-ui.html).

1. Open the Unity Editor, and go to **Window** > **Package Manager**.
2. In the **Package Manager** window, ensure **Unity Registry** is selected as the **Packages** type.
3. Navigate through the package list, find the **Advertisement Legacy** package, and then select the latest verified version.
4. Select **Install** or **Update**.

If you can't find the the **Advertisement Legacy** package in the list, try searching for it:

1. In the **Package Manager**, use the search bar and enter "Advertisement Legacy” or “Ads”.
2. The package will appear in either of these locations:

* **All** tab - listed as a package.
* **Services** tab - listed under **Monetization**.

If the package still doesn't appear, add the **Advertisement Legacy** package by its name:

1. In the **Package Manager** dropdown, select the plus button.
2. Select “Add Package by Name”, then enter `com.unity.ads` to search for it.
3. Select the latest verified version and select **Install** or **Update**.

> **Note:**
>
> Disabling [domain reloading](https://docs.unity3d.com/Manual/DomainReloading.html) in Play Mode Options is not supported for the Unity Ads package.

If you created your project through the Unity Editor flow, you must also link it to a Unity Ads Monetization dashboard Project ID before it can access Unity Gaming Services. Refer to [Configure a project for Unity Cloud](/cloud/projects/configure-project-for-unity-cloud.md).

**Next steps**: To continue your integration, refer to the [Initialize the SDK in Unity](/monetization/sdk-integration/unity-sdk/initialize-sdk.md) documentation.
