1. Write a list of the main entities and concepts in the domain.
This includes objects, processes, and roles.
Write a short paragraph explaining each main entity or concept's purpose and role in the system.
  1. Use Sequence Diagrams for workflows.
Sequence Diagrams will illustrate how objects interact with each other in a particular scenario.
They help understand the flow of operations and the roles of different components in the system.
  1. Create Class Diagrams.
I use class diagrams to show the structure of these entities:
  • attributes
  • methods
  • relationships
  1. Add links to the Code for Details.
Include references or links to the relevant sections of the codebase for those who want to explore implementation specifics in depth.
This is just an entry point; you can redirect people to your code, where the implementation details are.
  1. Invest in your Tests
Catching bugs early in the development cycle is a sweet treat.
Nothing replaces the confidence of running a good test suit.
I do all these things not because someone tells me to do it but because:
  • Save me time on every decision
  • keep the team on the same page
  • help onboarding new people (not just developers)
