TDD involves writing tests before code (red), writing just enough code to pass the test (green), then refactoring the code (refactor). The document discusses using test-driven development (TDD) and coding katas to practice TDD. It provides instructions on setting up a bowling kata in PHP using PhpSpec to learn TDD through incrementally developing tests and code for a bowling game scorekeeper class.
