+This deployable architecture creates observability instances in IBM Cloud and supports provisioning the following resources:
 
-- A resource group, if one is not passed in.
-- A Log Analysis instance.
-- A Cloud Monitoring instance.
-- Creates a Cloud Object Storage (COS) instance or supports using an existing one.
-- Supports creating KMS root keys in an existing KMS instance or using existing keys if creating new buckets.
-- Creates a KMS encrypted COS bucket that is required to store archived logs or using an existing bucket.
-- Creates a KMS encrypted COS bucket for setting up Activity Tracker event routing or using an existing bucket.
-- Supports configuring the Activity Tracker event routing to the Cloud Object Storage (COS) bucket and to the Log Analysis instance .
+* A resource group, if one is not passed in.
+* An IBM Cloud Log Analysis instance.
+* An IBM Cloud Monitoring instance.
+* An IBM Cloud Object Storage instance, if one does not exist.
+* The root keys in an existing key management service (KMS) if the keys do not exist. These keys are used when Object Storage buckets are created.
