# 2.1 VCN (basics)

This chapter is mostly written for those that are quite beginners with VCN \&Terraform in OCI.

*Some may consider the following explanation (for 2.1.1 & 2.1.2) quite unorthodox, but one must find the logic behind any kind of system/application before writing code.*

For starters, let's create a virtual network in a very simple manner - by using ["Start VCN Wizzard" ](https://docs.oracle.com/en-us/iaas/Content/Network/Tasks/quickstartnetworking.htm). This will allow us to get used to the environment,  and from there, to start writing the Terraform code for creating another VCN.
