+# Autonomous AI Database with a local standby
+
+This Terraform example creates an Autonomous AI Database with a local standby.
+
+You can run it by updating the file _terraform.tfvars_ file with the settings you want. 
+
+Enter your tenancy OCID, user OCID, user fingerprint, private key file path, region name, and compartment OCID. Change the other settings like database name and compute count to your liking.
