+# Integrate web frameworks with {{hosting}}
+
+{{firebase_hosting}} integrates with popular modern web frameworks including Angular
+and Next.js. Using {{firebase_hosting}} and {{cloud_functions_full}} with these
+frameworks, you can develop apps and microservices in your preferred framework
+environment, and then deploy them in a managed, secure server environment.
+Support during this early preview includes the following functionality:
+
+* Deploy Web apps comprised of static web content
+* Deploy Web apps that use pre-rendering / Static Site Generation (SSG)
+* Deploy Web apps that use server-side Rendering (SSR)—full server rendering on demand
+
+Firebase provides this functionality through the {{firebase_cli}}. When initializing
+{{hosting}} on the command line, you provide information about your new or existing
+Web project, and the {{cli}} sets up the right resources for your chosen Web
+framework.

+
+## Serve locally
+
+You can test your integration locally by following these steps:
+
+1. Run `firebase emulators:start` from the terminal. This builds your app and
+   serves it using the {{firebase_cli}}.
+2. Open your web app at the local URL returned by the {{cli}} (usually http://localhost:5000).
+
+## Deploy your app to {{firebase_hosting}}
+
+When you're ready to share your changes with the world, deploy your app to your
+live site:
+
+1. Run `firebase deploy` from the terminal.
+2. Check your website on: `SITE_ID.web.app` or `PROJECT_ID.web.app` (or your custom domain, if you set one up).
+
+## Next steps
+
+See the detailed guide for your preferred framework:

+* [Angular Universal](/docs/hosting/frameworks/angular)
+* [Next.js] (/docs/hosting/frameworks/nextjs)
+* [Frameworks with Express.js](/docs/hosting/frameworks/ßexpress)
