-In Delphix, an environment is either a single instance host or cluster of hosts that run database software. 
-Environments can either be a source (where data comes from), staging (where data are prepared/masked) or target (where data are delivered and used by developers and testers). 
-Each environment has its own properties and information depending on the operating system, installation, purpose, etc. 
-The Delphix Environment resource allows Terraform to create, update, and delete Environments. This specifically enables the `apply`, `import`, and `destroy` Terraform commands. 
-Updating existing Delphix Environment resource parameters via the `apply` command is supported for the parameters specified below.   
+In Delphix, an environment is either a single instance host or a cluster of hosts that runs your databases. Environments can either be: 
+- Source: where data originates. 
+- Staging: where data is prepared for ingestion. . 
+- Target: where data is delivered and used by developers and testers. 
+   - Note: Sometimes “Staging” is considered an intermediary environment which temporarily hosts a database for masking, subsetting, or synthetic data purposes. In virtualization, this is considered a Target environment.
