Installing the Unity SDK
To ensure that you are using the latest version of Unity Ads, we recommend that you install the SDK package from the Unity Editor Package Manager.
In the Unity Editor, select Window > Package Manager.
In the Package Manager window, select the Advertisement package from the list, and then select the most recent verified version.
Select Install or Update.
If you created your project through the Unity Editor flow, you must also link it to a Unity Dashboard Project ID before it can access Unity Gaming Services. See Configuring projects for Unity Gaming Services.
