 ### 1. Create Network
-Follow the below steps to create Network that includes VCNs, Subnets, DHCP, DRG, Security List, Route Tables, DRG Route Tables, NSGs, etc.
+Creation of Networking components using Automation Toolkit involes four simple steps.
+ - Feeding the details of networking resources to Excel.
+ - Running the toolkit to generate auto.tfvars.
+ - Executing Terraform commands to provision the resources in OCI.
+ - Exporting the details of Security Rules and Route Rules to CD3 Excel Sheet.

+Below are the steps in detail to create Network that includes VCNs, Subnets, DHCP, DRG, Security List, Route Tables, DRG Route Tables, NSGs, etc.
 
 1. Choose appropriate excel sheet from [Excel Templates](/cd3_automation_toolkit/documentation/user_guide/Essentials_of_Automation_Toolkit.md#excel-sheet-templates) and fill the required Network details in the Networking Tabs - VCNs, DRGs, VCN Info, DHCP, Subnets, NSGs tabs.

+### 1a. Use an existing DRG in OCI while creating the network
+In some scenarios, a DRG has already been created in the tenancy and rest of the Network components still need to be created. In such cases, generate the networking related tfvars using same process mentioned above till Step 4.
