The add-on's entry in\nMarketplace is referred to as the **listing**.\n\nListing fields\n--------------\n\nAn add-on listing allows users to preview and install your add-on. You control\nthe information and screenshots in the listing. You can provide titles and\ndescriptions in multiple languages.\n\n**Figure 1.** A Classroom add-on listing as viewed by a teacher.\n\nA \"Works with Classroom\" label is automatically applied to your\nlisting. See [Listing settings](/workspace/classroom/add-ons/developer-guides/project-configuration#workspace_marketplace_name-listing) to learn about configuration details for\nClassroom add-ons.\n\nInstallation\n------------\n\nAn add-on must be *installed* before users can select it in the Classroom UI.\nUsers can install the add-on by clicking the buttons at\nthe top of the listing.\n\n### Installation options\n\nAll add-ons can be installed by an administrator. You can optionally choose to\nalso allow *individual* installation.\n| **Key Point:** Users can see more than one installation option depending on the user's role in the domain. Teachers can only install an add-on for themselves, but administrators can install an add-on for themselves and others.\n\n#### Individual installation\n\nIndividual installation adds the add-on to the user's own account only. This is\nthe only installation type that teachers can perform. The installing user is\nprompted to consent to the add-on's access scopes.\n\nAdministrators can restrict individual installation to approved add-ons only by\nsetting up a Google Workspace Marketplace allowlist. See [Individual\ninstallation](/workspace/classroom/add-ons/developer-guides/project-configuration#individual_installation) for more information about this user experience and configuration.\n\n#### Administrator installation\n\nAdministrator installation adds the add-on to users in specific organizational\nunits or all accounts in the domain. Only domain administrators can perform this\ntype of installation. The administrator can consent to all access scopes on\nbehalf of all users in the domain.\n\nSee [Installation settings](/workspace/classroom/add-ons/developer-guides/project-configuration#installation-settings) for configuration details."]]
