 # Oracle Cloud Infrastructure Provider
 
-The Oracle Cloud Infrastructure provider is used to interact with the many resources supported by the [Oracle Cloud Infrastructure](https://cloud.oracle.com/cloud-infrastructure). The provider needs to be configured with credentials for the Oracle Cloud Infrastructure account.  
+The Oracle Cloud Infrastructure (OCI) provider allows you to use Terraform to interact with [Oracle Cloud Infrastructure](https://cloud.oracle.com/cloud-infrastructure) resources. Wherever you use a Terraform distribution you can use the OCI Terraform provider, including [Terraform Cloud](https://www.terraform.io/docs/cloud/index.html) and the OCI [Resource Manager](#resource-manager).
 
-Use the navigation to the left to read about the available resources.
+## Terraform CLI
 
-~> **Note:** Please visit our new OCI Provider documentation at [official Oracle Cloud Infrastructure documentation](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraform.htm) for tutorials, examples and best practices. Service reference documentation will continue to be available on this [page](https://registry.terraform.io/providers/hashicorp/oci/latest/docs).
+For details on configuring the OCI Terraform provider and using it with the Terraform CLI, refer to the [official OCI Terraform provider documentation](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraform.htm), which includes:
 
+- How to [install the provider](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraforminstallation.htm)
+- How to [configure the provider](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformproviderconfiguration.htm)
+- Ways you can [describe your infrastructure](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformdescribingyourinfrastructure.htm)
+- How to [apply your configurations](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformapplyingyourconfigurations.htm)
+- [Example configurations and solutions](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformexamples.htm)
+- Troubleshooting [basics](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformtroubleshootingbasics.htm) and [common issues](https://docs.oracle.com/en-us/iaas/Content/API/SDKDocs/terraformtroubleshooting.htm)
+
+As you write your configuration files, use the left navigation panel on this page to access detailed information about each supported resource and data source.
+
+## Resource Manager
+
+The Oracle Cloud Infrastructure [Resource Manager](https://docs.oracle.com/en-us/iaas/Content/ResourceManager/Concepts/landing.htm#ResourceManager) is an Oracle-managed service that is based on Terraform and uses Terraform configuration files to automate deployment and operations for the OCI resources supported by the OCI Terraform provider.
+
+Resource Manager allows you to share and manage infrastructure configurations and state files across multiple teams and platforms. This infrastructure management can't be done with local Terraform installations and Oracle Terraform modules alone. See the [Overview of Resource Manager](https://docs.oracle.com/en-us/iaas/Content/ResourceManager/Concepts/resourcemanager.htm) for more information.
