 ### Breaking Changes
 * When using `paving` for creating a foundation,
-  there are instances of provisioned that may not be used.
+  there are instances provisioned that may not be used.
   For example, only deploying Ops Manager and PAS tile,
-  but still have networking resources created for PKS.
+  but still having networking resources created for PKS.
 
   This update allows control over that.
-  The terraform resource have been organized into namespaced files.
+  The terraform resources have been organized into namespaced files.
   The namespacing identifies the resources and what they are for.
   For example, `pas-iam.tf` creates IAM resources for PAS tile.
   There are corresponding namespaces for `ops-manager-*.tf` and `pks-*.tf`.
 
-  If you don't require PAS, to `rm pas-*.tf`.
-  If you don't require PKS, to `rm pks-*.tf`.
+  If you don't require PAS, run `rm pas-*.tf`.
+  If you don't require PKS, run `rm pks-*.tf`.
 
   OpsManager resources cannot be removed as Ops Manager is required.
 
   This change also affects the `stable_config` pattern of outputs.
-  Because of a limitation of `terraform`, no way to test the existence of a resource,
-  `stable_config` has to be separated by Ops Manager `stable_config_opsmanager`, PAS `stable_config_pas`, and PKS `stable_config_pks`.
+  Because there is no way to test the existence of a resource in `terraform`,
+  `stable_config` has to be separated by Ops Manager `stable_config_opsmanager`,
+  PAS `stable_config_pas`, and PKS `stable_config_pks`.
 
   These changes are on all IAASes.
   NOTE: `nsxt` does not have paving resources for PKS, which is why prefixed files are not there.
