After you have selected the template that corresponds to your needs, you can open the project file in Workbench. The project files are archived as .wbpz files, and so to open them, you can: use the Restore Archive option under the File menu in Workbench; browse to the file, unzip it, and then open it in the normal fashion; or, in Windows, browse to the file and double-click it.

Two or three systems will then appear in the Project Schematic: a Polyflow system connected to a Results system and, in cases where a geometry is provided, a Mesh system connected to the Polyflow system. A Parameter Set bar allows you to modify the parameters, design points, and properties.

It is recommended that you run the calculation at least once with the provided geometry/mesh, in order to get some experience with the template. You can then hook your own geometry/mesh, modify the values defined by the Parameter Set bar to suit your needs (see the HTML report in the template directory for a summary of the predefined values), and simply click the Update Project button. If the nature of the predefined values do not fit your needs, you can open Polydata via the Setup cell of the Polyflow system and adapt any of the details.

Note that the HTML report is not generated automatically, and so you must use the File/Report/Publish menu option in CFD-Post if you want a report.
