 # <provider> Delphix Provider
 
-!> **NOTE**
-The Terraform Provider for Delphix requires the Delphix Continuous Data Platform and Data Control Tower (DCT).
+The Terraform Provider for Delphix enables customers to natively manage data-as-code along with their infrastructure.
+With Terraform and Delphix, customers can now automatically provision, manage, and teardown any number of ephemeral data environments to drive enterprise DevOps workflows, such as test data management.
 
+This provider communicates directly with Data Control Tower (DCT) to generated virtual database and other objects. Therefore, DCT must be registered with one or more Delphix Continuous Data Engines.

+## System Requirements
+
+| Product                        | Version  |
+|--------------------------------|----------|
+| Data Control Tower (DCT)       | v14+ |
+| Delphix Continuous Data Engine | v6.0.0.1+ |
+
+Note: The DCT version above guarantees full provider support. However, each  resource might support older versions. Refer to the specific resource documentation page for more information.
+
+## Connectivity and Authentication
 
-This provider leverages the Delphix APIs available with the Delphix Data Control Tower (DCT). The provider must be configured with the proper API key generated by DCT and registered with associated Delphix engines before use
+All communication is performed through HTTPS. The Delphix Provider uses Data Control Tower (DCT) APIs to communicate with Delphix Continuous Data Engines. 
 
-To learn more about Delphix and DCT APIs, refer to [Delphix Docs](https://docs.delphix.com) and [DCT Docs](https://docs.delphix.com/dct) respectively. Please [Contact us](ask-integrations@delphix.com) (ask-integrations@delphix.com) with any questions.
+Authentication with DCT APIs are managed using API Keys. For generation of an API key, please refer to [DCT API Keys](https://dct.delphix.com/docs/latest/api-keys).
 
 ## Example Usage
 
+The following script demonstrates how to configure the Delphix Provider to connect with Data Control Tower and then provision a VDB. Additional resource guides and documentation can be found on the left hand side.

-## Configuration and API Key Generation
-
-Delphix Provider uses DCT APIs to communicate with the Delphix engines. Authentication to DCT APIs are handled using API Keys.
-For generation of the API key, please refer to [Authentication](https://docs.delphix.com/dct/authentication-170164311.html).

+### Example Global Parameter Reference
 
-## Argument Reference
+* __host__: The hostname for DCT.
+* __key__ : The API Key which is used to authenticate with DCT. (Example `apk 2.abc123...`).
+* __tls_insecure_skip__: (Optional) A boolean value which determines whether to skip the SSL/TLS check. The dfault value is `false`. Skipping any SSL/TLS check is not recommended for production environments. 
+* __host_scheme__: (Optional) Determines the configured host URL's scheme. The default value is `https`.
 
-* __key__ : The API key is provided in this field that gets passed on to DCT for authentication.
-* __host__: The host name for where DCT APIGW is running.
-* __tls_insecure_skip__: This takes a boolean value which determines whether to skip the TLS check. tls_insecure_skip is really unsafe to set it to true. By default it is `false`.
-* __host_scheme__: Determines the host scheme configured. By default it is `https`.
