PlantUML to the fullest: Automation and life hacks for sequence diagrams

Have you heard of PlantUML? Bet you didn't know about custom functions. First time you've heard of it? Then you are welcome on board. I will demonstrate the detailed guide and talk about the breadth of PlantUML's capabilities, specification autocollection and ways to use colour differentiation.
Together, we will be convinced of the full power of the tool on examples from practice. In addition, we will discuss the following aspects:
• Methods for lightweight online and secure offline editing.
• Team work approach with code import.
• Possible restrictions.

The presentation will include the source code, which can (and should) be copied and adopted in your own work.
