Stella has a broad variety of features, but it's very easy to get started. The Model Building Tutorial will walk you through the process of creating a simple model (for Professional or Architect users). Building a Simple Interface goes through the process of creating an interface and publishing it (for Designer and Architect users). Both provide step by step instructions that will help you get familiar with the basic mechanics of using the software. Example Models shows how some of the different functionality in the software is used in models.
