# Installing Qt 6 SDK

The Qt SDK includes the tools you need to build desktop or embedded applications. You can grab the latest version from the [Qt Company](https://qt.io)’s homepage. There is an offline and online installer. The author personally prefers the online installer package as it allows you to install and update multiple Qt releases. This is the recommended way to start. The SDK itself has a maintenance tool, which allows you to update the SDK to the latest version.

The Qt SDK is easy to install and comes with its own IDE for rapid development called *Qt Creator*. The IDE is a highly productive environment for Qt coding and recommended to all readers. Many developers use Qt from the command line, however, and you are free to use the code editor of your choice.

When installing the SDK, you should select the default option and ensure that at least Qt 6.2 is enabled. Then you’re ready to go.

## Update Qt

The Qt SDK comes with an own maintenance tool located under the `${install_dir}`. It allows to add and/or update Qt SDK components.

## Build from Source

To build Qt from source you can follow the guide from the [Qt Wiki](https://wiki.qt.io/Building_Qt_6_from_Git).

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.novaflowos.com/start/qt6-qml-book/readme/ch02-start/install.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
