The document describes how to create a timing diagram by defining states, participants, and matching states to participants. It explains that a timing diagram shows timing data on a lifeline with messages exchanged between states. It provides an example process of withdrawing cash from an ATM to illustrate defining the states like inserting a card, entering a PIN, selecting an amount. The states are then matched to the participants in the process, which are the customer, card reader, and bank system.
