Handbook

A handbook is a book that tells you all the important things you need to know. It is like a big guidebook that helps you understand what you need to do in different situations. A handbook is usually given to you when you start a new job or start going to a new school or club. The handbook will tell you all the rules you need to follow, like how to behave properly and what you are allowed and not allowed to do. It will also tell you what to do if you have a problem or if you need help. Think of a handbook like a map that helps you navigate a new place - it tells you where to go and what to do so you can be successful and happy!
