Text annotation is the standard comment shape that can be used to describe or give additional information about a single shape in the Process. Unlike Group shape, which is better used to name and describe a set of shapes, Text annotation is best used to comment a single shape in the Process, giving more information to either developers or support personnel to identify common/known issues or on how to continue developing the Process if it's still in development.
Text annotations can be used to comment your Processes, to explain different actions or unclear functionality.
