There are three short Introduction Tutorials, each one applying features associated with the BOS User Guidance profiles using a step-by-step example in BOS 5.6.1.
The same example is carried through all three tutorials. Start at the beginning "from scratch" and build the example step by step through all three tutorials.
Or, if you prefer to start with Process Definition or Application design, import the appropriate process diagram from Community Contributions to start with and advance it further in your own Bonita Studio.
