This procedure enables you to use a form to define the text and images that appear in the extension app listing in the [Docusign App Center](/extension-apps/extension-apps-101/app-center). Instead of using a form, you can define the settings by [creating](/extension-apps/build-an-extension-app/register/use-manifest) or [updating](/extension-apps/build-an-extension-app/update-registration/use-manifest) a JSON app manifest file. ## Access App Center listing for an extension app To access an extension app's App Center listing: 1. Log in to the [Developer Console](https://devconsole.docusign.com). 2. On the **My Extension Apps** page, locate the row for the extension app you want to update. 3. Select the app to open the **Overview** page. 4. In the left navigation, select **App Center Listing**. ![App Center Listing page](/_fern-files/_img/e1d0fa29538e4d74ac61deeb0f9005b4ad16a484006aace449a9e2b162888107.webp) 5. If the extension app registration is newly created, define these settings: * [Screenshots](/extension-apps/build-an-extension-app/register/use-form/app-center-listing#manage-screenshots) * [Basic information](/extension-apps/build-an-extension-app/register/use-form/app-center-listing#update-basic-information) * [App icon](/extension-apps/build-an-extension-app/register/use-form/app-center-listing#update-app-icon) * [Publisher details and contact information](/extension-apps/build-an-extension-app/register/use-form/app-center-listing#update-publisher-details-and-contact-information) * [Distribution details](/extension-apps/build-an-extension-app/register/use-form/app-center-listing#update-distribution-details) If you are updating an existing extension app's registration, you can modify only the settings you want to change. If you are updating the registration for a published extension app, you must supply a list of changes for the [changelog](/extension-apps/build-an-extension-app/register/use-form/app-center-listing#update-changelog). ## Manage screenshots Screenshots appear with your extension app listing in the [Docusign App Center](/extension-apps/extension-apps-101/app-center). You can provide a maximum of four images. The screenshots will be displayed in the order in which you upload them. Each screenshot must have a 16:10 aspect ratio. Permitted dimensions range from a minimum of 848x530 pixels to a maximum of 1600x1000 pixels. Docusign recommends using the maximum size. The maximum file size per image is 5 MB. The allowed file types are JPEG and PNG. **To add a screenshot:** 1.
