The Getting Started tabs in the vSphere Client connected to vCenter Server provide a wizard to help you set up a basic inventory quickly.

Setting up a basic inventory with the Getting Started tabs after you install vCenter Server involves the following tasks:

Creating a datacenter

Adding the host to the datacenter

Creating a virtual machine

You must have an empty vCenter Server inventory to view the Getting Started tabs wizard. After you have set up the basic inventory, the Getting Started tabs continue to provide information about inventory objects but no longer provide inventory setup wizard help.
