This document outlines the basics of four Scrum ceremonies: Sprint Planning, Daily Scrum, Sprint Review, and Sprint Retrospective. Sprint Planning involves defining sprint goals, clarifying requirements, and planning work. The Daily Scrum is a daily meeting to improve coordination and plan the next 24 hours. The Sprint Review demonstrates the product increment to stakeholders and gathers feedback. The Sprint Retrospective focuses on process improvements for future sprints. Each ceremony has defined inputs, participants, duration, outputs, and occurrence within the sprint cycle.
