In this section, the developer will talk about what has been refactored and which files/components were refactored.
In this section, the developer will compare how the code was before the refactoring with how the code was after the refactoring. For example, they can try to answer the question "How did the refactoring made the code more easy to read or maintain?".
It is highly suggested that the developer put a diagram explaining the modified architecture.
In this section, the developer reflects about why the refactor was needed and how it is possible in the future to write code in a better way so that the necessity to refactor happens less often.
