If you need\nmultiple configurations of the extension, you can install the extension multiple\ntimes, with a different configuration for each instance you install.\n\nWith extensions,\nyou don't spend time researching, writing, and debugging the code that\nimplements functionality or automates a task for your app or project.\n\nTo install or manage extensions, you must be assigned one of these roles:\n[Owner or Editor](/docs/projects/iam/roles-basic) or\n[Firebase Admin](/docs/projects/iam/roles-predefined-all-products).\n\nTo install an extension, your project must be on the **Blaze** (pay as you\ngo) plan. Although there is no charge for installing an extension, you might be\ncharged for your use of Firebase services or Cloud services such as\n[Cloud Secret Manager](https://cloud.google.com/secret-manager/pricing), if your usage exceeds the services' free\ntier.\n\nYou can also evaluate extensions before installing them on a project using the\nExtensions emulator, a component of the Firebase Local Emulator Suite.\n\nOfficial Firebase extensions\n\nThe **official Firebase extensions** are developed and tested by Firebase\nand Firebase Extensions partner services. These extensions are reliable and\nsecure.\n\nBrowse Firebase extensions\n\nBrowse Firebase extensions in the [Extensions Hub](https://extensions.dev/extensions).\n\nView the source code of an extension\n\nTo find a link to the source code for an extension,\nclick **Learn more** on the extension's card in the Extensions Hub.\n\nContents of an extension's source code\n\nAn extension's source directory includes:\n\n- **extension.yaml file** --- Contains the extension's metadata and defines\n the [resources](#resources) created, the Google APIs and\n [access roles](/docs/extensions/permissions-granted-to-extension) required for\n operation, and any user-configured parameters (environment variables) for the\n extension\n\n- **functions directory** --- Contains the files for the source code for the\n extension\n\n- **README file** --- Lists the extension's metadata (but in more\n human-readable format) as well as the content from the PREINSTALL file\n\n- **PREINSTALL file** --- Describes how the extension works, any necessary\n pre-installation tasks, configuration requirements, and details about the\n extension\n\n- **POSTINSTALL file** --- Describes specific usage instructions and any further\n integration requirements\n\nResources for an extension\n\nEvery Firebase project contains several types of \"resources\". Project resources\ncan include things like deployed Cloud Functions, database instances,\nCloud Storage buckets, Cloud Scheduler jobs, and Cloud Secret Manager data.\n\nWhen you install an extension, Firebase creates new *extension-instance-specific*\nresources in your project. These resources are required by the extension to\noperate.\n\nNote that, if you [uninstall an instance of an\nextension](/docs/extensions/manage-installed-extensions#uninstall), all the\nresources that Firebase created specifically for that instance of the extension\nto operate (like a set of functions) are deleted. However, the following are\n***not*** deleted:\n\n- Any artifacts created by the extension (like stored images).\n\n- Any other resources in your project, like a database instance or Cloud Storage\n bucket. Even if the extension interacted with these other resources, they\n are not *extension-specific*, so they aren't deleted if the extension is\n uninstalled.\n\nUsing the Firebase console, the Firebase CLI, or autogenerated SDKs {: #console-vs-cli}\n\nYou can install and manage extensions using\neither the\n[Firebase console](/docs/extensions/install-extensions?platform=console)\nor the\n[Firebase CLI](/docs/extensions/install-extensions?platform=cli),\nor in code using\n[autogenerated SDKs](/docs/extensions/install-extensions?platform=sdk).\n\n| **Action** | **Firebase console** | **Firebase CLI** | **Autogenerated SDK** |\n|----------------------------------------------|----------------------|------------------|-----------------------|\n| View detailed information (pre-installation) | | | |\n| Install | | | |\n| View configuration (post-installation) | | | |\n| Edit configuration | | | |\n| Update version | | | |\n| Uninstall | | | |\n\nNext Steps\n\n- View detailed information about an extension before you install the extension\n ([Extensions Hub](https://extensions.dev/extensions) or\n [Firebase CLI](/docs/extensions/install-extensions#view-details)).\n\n- Install an extension into your Firebase project using either the\n [Firebase console](/docs/extensions/install-extensions?platform=console),\n the [Firebase CLI](/docs/extensions/install-extensions?platform=cli).\n or [autogenerated SDKs](/docs/extensions/install-extensions?platform=sdk)."]]
