#### Create Application Map <a href="#create-application-map" id="create-application-map"></a>

Go to [create an application map](/harness-ai/use-harness-platform/application-map.md#create-application-map) and follow the steps, except, navigate to **Chaos** module, and select **Project Settings**, and then select **Discovery**.

**NOTE**

Alternatively, navigate to **Chaos** module -> **Application Maps** -> **Manage Discovery in Project Settings**. This also leads you to the page in step 2.

{% endhint %}

In the step where you select one or more discovered services, choose a specific service on which you want to inject chaos, and click **Next**.
