Click the 
Create database
 button in the Cloud Firestore section at the top of the 
page. Security rules dialog will open:
Two security modes are offered to you. 
Test
 mode will allow anyone to have read and 
write access to the database while the 
locked
 mode will deny all reads and writes to 
the database. Choose the test mode for now. You'll learn more about the security of 
the Cloud Firestore in the "Chapter 19: Securing data in Cloud Firestore".
Click the 
enable
 button.
Your database will open after Firebase finishes creating it. This what you'll see:
