 ### Example Scenes
-In the example code, we provide four example Unity scenes, showcasing various ways to integrate the Momento SDK with Unity. The first two require ensuring the `MOMENTO_AUTH_TOKEN` environment variable is set, or copying and pasting your auth token into `Assets/Scripts/TopicsTest.cs` (or `Assets/Scripts/TopicsTestCoroutine.cs`) replacing `ADD_YOUR_TOKEN_HERE` in the `ReadAuthToken()` function (hard-coding your auth token in code is not recommended but can be used for testing purposes if necessary).
+In the example code, we provide four example Unity scenes, showcasing various ways to integrate the Momento SDK with Unity. The first two require ensuring the `MOMENTO_API_KEY` environment variable is set, or copying and pasting your auth token into `Assets/Scripts/TopicsTest.cs` (or `Assets/Scripts/TopicsTestCoroutine.cs`) replacing `ADD_YOUR_TOKEN_HERE` in the `ReadAuthToken()` function (hard-coding your auth token in code is not recommended but can be used for testing purposes if necessary).
 - `MomentoTopicsDemo.unity` (using `TopicsTest.cs`): utilizes `Task.Run()` to run the subscription to the Momento Topic in a background thread. This is the approach descirbed above. This code is based upon the [Momento .NET SDK Topic Example](https://github.com/momentohq/client-sdk-dotnet/tree/main/examples/TopicExample).
 - `MomentoTopicsDemo-Coroutine.unity` (using `TopicsTestCoroutine.cs`): identical to the previous scene except that it utilizes Unity Coroutines to run the subscription asyncronously in the main thread.
 - `MomentoTopicsDemo-TokenVendingMachine.unity` (using `TopicsTestTokenVendingMachine.cs`): utilizes the example [Momento Token Vending Machine](https://github.com/momentohq/client-sdk-javascript/tree/main/examples/nodejs/token-vending-machine) to obtain a temporary, restricted scope Momento auth token. This is beneficial because (1) we no longer need to hard-code in a specific auth token into the app, and (2) we can utilize a `tokenId` embedded in the Topics message to more securely know which client/username sent a specific message. Note that you'll need to explicitly setup the Token Vending Machine separately and then specify its URL via the `tokenVendingMachineURL` variable specified in `TopicsTestTokenVendingMachine.cs`.
