If you want to develop your own workflow, the easiest and most reliable approach is to make simple modifications to the default workflows (for example, edit a state name). It is strongly recommended that you modify the default workflows rather than create a new workflow from scratch, especially if you have little or no experience with these concepts.
Some of the things that you can customize include:
Current State ---- Action 1 ---> New State 1 Current State ---- Action 2 ---> New State 2
Familiarize yourself with the concepts of state diagrams and actions, also called state transitions.
