This preparatory step does not require a custom HTML template. The purpose of this step is to make the rest of the Host On-Demand desktop page easier to see by reducing the size of the sessions window.
Use the Deployment Wizard to edit StandardSupplies.html.
Use the browser to run StandardSupplies.html as a Host On-Demand client. The resulting default Host On-Demand desktop page is shown below. Notice that the sessions window is smaller than it was in Step 4.
