## What it is
The source for 'Qt5 Cadaques', a free open-source book teaching Qt5 and QML/Qt Quick development, built with Sphinx and published at qmlbook.org. The repository contains the book text (CC BY-NC-SA 4.0) plus BSD-licensed code examples and tooling for generating HTML, single-page, and PDF builds.

## Use cases
- learn QML and Qt Quick from scratch
- free Qt5 book pdf download
- tutorial on model-view-delegate in Qt Quick
- learn to extend QML with C++
- examples of particle simulations and shader effects in QML
- introduction to Qt Creator and Qt5 SDK

## When to choose
- you are learning Qt5/QML and want a structured, free, well-illustrated book
- you want runnable code examples licensed permissively (BSD)
- you want to contribute to or fork an open Qt learning resource

## When to avoid
- you need Qt 6 coverage - the book targets Qt5 and its last build was 2020
- you need a commercial-licensed book text (content is CC BY-NC-SA)
- you need up-to-date tooling or active maintenance
