+This quickstart demonstrates using the **Firebase SDK for Cloud Functions** with an HTTPS trigger through building an endpoint returning the current time.
 
 
 ## Introduction
 
-We'll show a series of basic HTTPS triggered Functions.
+The function `date` simply returns the current server date. You can pass it a `format` URL Query parameter to format the date.

 ## Try the sample
 
-To try the samples please follow the [HTTPS trigger documentation](https://firebase.google.com/preview/functions/gcp-https)
+You can first simply hit the Function URL directly. After deploying the function you can simply open the following URLs in your browser:
+
+```
+https://us-central1-<project-id>.cloudfunctions.net/date
+
+https://us-central1-<project-id>.cloudfunctions.net/date?format=MMMM%20Do%20YYYY%2C%20h%3Amm%3Ass%20a
