 You must initialize Firebase Hosting in order to deploy your application. In order to do this run the `firebase init` command.
-This command prompts you to give the public directory. Choose the /dist directory created by the `ng build -prod`. 
-`firebase init` will also ask you if you want to overwrite your index file. Type `no` since your angular app includes a index file.

+Note: If you haven't installed the Firebase CLI yet, run this command:

+- This command prompts you to enter a public directory. Enter `dist` (generated by `ng build -prod`).
+- The command will also ask you if you want to overwrite your index file. Type `n` since your Angular app includes a index file.
+- This command also prompts you whether to configure the project as a single-page app. Enter `y` if you're using Angular Router or similar. Otherwise, enter `n`.

 ### `auditTrail()`

 **What is it?** - Returns an Observable of `DocumentChangeAction[]` as they occur. Similar to `stateChanges()`, but instead it keeps around the trail of events as an array.
 
 **Why would you use it?** - This method is like `stateChanges()` except it is not ephemeral. It collects each change in an array as they occur. This is useful for ngrx integrations where you need to replay the entire state of an application. This also works as a great debugging tool for all applications. You can simple write `afs.collection('items').auditTrail().subscribe(console.log)` and check the events in the console as they occur.
