Preliminaries

Preliminaries are the foundational concepts and basic information needed before diving into a main topic or detailed analysis. Think of them as the introductory steps that set the stage, ensuring everyone understands the essential terms, principles, or background. They help create a common starting point, making complex discussions or studies easier to follow and more meaningful. In essence, preliminaries are the necessary groundwork that prepares you for the main content or advanced work to come.
