The first step is creating a reporting project. A reporting project is a set of configuration files that tell Horizon Reports how it works with your data. When you launch Horizon Reports for the first time, you’ll automatically be prompted to create a project. Alternately, you can use the New menu item under the Project menu in Horizon Reports Studio. See the Creating a New Project topic for details.
Horizon Reports will scan your data and create a reporting project, and then you’re then ready for Step 3.
