# Introduction Welcome to Flutter Internals, a **community-maintained** open source book providing a guided tour through Flutter's implementation. This book is very much a "work in progress"; in fact, we'd **love your help** with grammatical fixes, technical edits, and new content. [**Click here**](https://app.gitbook.com/invite/flutter-internals?invite=-Lz8eupmUYQGm6UH34Dq) to become a contributor. ## What is this book? * The goal of this book is to provide intuitive descriptions of Flutter’s internals in an easily digestible outline format. * Descriptions are intended to be comprehensive without becoming bogged down in implementation details or sacrificing clarity. * This book strives to provide a “hawk’s eye view” of Flutter’s implementation. ## Who is the audience of this book? * These notes are most useful once you have a solid understanding of how to use Flutter (since they describe how the interfaces actually work). * This outline was written for developers looking to build intuition about Flutter internals and Flutter hackers looking to ramp up on the codebase. * We also hope that this book can inspire more thorough learning materials (such as deep dive videos or long form articles). ## Who can contribute to this book? * Anyone (thank you)! If there’s a corner of the framework that you find confusing, please consider [becoming a contributor](https://app.gitbook.com/invite/flutter-internals?invite=-Lz8eupmUYQGm6UH34Dq) and updating the book with the relevant details. * **Please read the "Get Involved" section.** --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
