+Angular CLI introduced `deploy` command in version 8.3.0. By default, this command will execute the `deploy` [CLI builder](https://angular.io/guide/cli-builder) associated with your project. Currently, there are third-party builders which implement deployment capabilities to different cloud platforms:

+You can read how to use the listed deployment builders following the links associated with each package name above.
+
+For example, to automatically deploy to Firebase via the `ng deploy` command run:
+
+<code-example language="none" class="code-shell">
+ng add @angular/fire
+ng deploy
+</code-example>
+
+The command above will:
+
+- Authenticate you using your Firebase account. If you don't already have a Firebase account, you will need to create one.
+- Let you select a Firebase project you want to deploy to.
+- Produce optimal build of your application equivalent to `ng deploy --prod`.
+- Upload your assets to Firebase hosting.
+
+If you're deploying to a self managed server or there's no builder for your favorite cloud platform you can either:
+
+- Create a new builder to utilize the `ng deploy` command
+- Read through the sections below to learn how to manually deploy your app

 ### Basic deployment to a remote server
 
 For the simplest deployment, create a production build and copy the output directory to a web server.
