> [!NOTE]
> **Note:** Apigee Extensions are available in the Edge UI to Google Cloud Apigee customers with an Enterprise [support](https://cloud.google.com/apigee/pricing) plan.

You add an extension by selecting the one you want from a list of available extension packages
for the Apigee Edge organization.

**To add a new extension instance:**

1. Sign in to the Edge UI as an **organization administrator** . You must be an **organization administrator** to add an extension.
2. Click **Extensions \> Admin** .

   The **Extensions** view displays a list of all extensions that have been
   configured from extension packages available on the system.

   In the next steps, you'll add your own extension.
3. Click **Add Extension** :

   ![](https://docs.apigee.com/static/api-platform/images/extensions-add-extension-button.png)

   The **Select an extension** view displays. This page lists all of the
   extensions available on the system. The extensions in the list are divided between those
   developed by Google and those developed by other companies.

   To make an extension available for use from an API proxy, you select an extension package,
   configure an extension with values specific to your needs, then deploy it to an
   environment.

   You'll do that in the next steps.
4. On the **Google** tab, locate the **Google Stackdriver Logging** extension package.
5. To view more information about the extension, click **View Details** :

   In the extension's details view, you can find information about the extension's author,
   license, source repository, and so on.
6. To configure an instance of this extension, click the **Select** button:

7. In the **Extension Properties** dialog box, enter the following values:

   | Field | Required? | Description |
   |---|---|---|
   | **Name** | Required | Enter a name for this extension, such as "my-logging-extension" (don't use spaces or special characters). This value must be unique in the organization. In your own extensions, try to use a name that says something about what the extension configuration does. |
   | **Description** | Optional | For your own extensions, enter a description that will help an API proxy developer understand what this configuration of the extension does. Remember that it's possible for there to be multiple configurations of the same extension in an organization. Imagine you're telling the proxy developer what the extension is for. |

8. Click **Create** .

   Edge creates your new extension.
