\title Get and Install Qt
\brief Downloading and installing with \QOI or \QMT.
You can get Qt, its modules and tools via \QOI or \QMT.
Via \QOI you can do new installations. \QMT is included in each Qt installation
and with it you can update your Qt installation for example by adding and
removing components.
You can use \QOI and \QMT via a graphical user
interface or a command line interface. The command line interface
enables installing and uninstalling without any user interaction, that is,
unattended usage.
To learn the basics of getting and installing Qt, take the
\l {https://www.qt.io/academy/course-catalog#how-to-install-qt}
{How to Install Qt} course in Qt Academy.
\section1 Using \QOI
You can download \QOI via \l{https://login.qt.io}{Qt Account}
as follows:
\list 1
\li Select \uicontrol{Downloads}
\li Download \QOI for your host: Linux, macOS, or Windows
\endlist
See \l{Get and Install Qt with \QOI} for more information
about how to use \QOI.
\l{Get and Install Qt with Command Line Interface} describes how you can use
\QOI with the command line interface.

\section1 Using \QMT
Once Qt is installed, you can use \QMT under <install_dir>
to add components and to update or remove installed components. \QMT is
included in each Qt installation.
For more information about how to use \QMT with the command line
interface, see \l{Get and Install Qt with Command Line Interface}.

\section1 Building Qt from sources
You can also build Qt yourself. This can be useful in many
scenarios, for example, if no prebuilt packages exist for your
platform, if you need to modify Qt during debugging, or if you plan
to contribute to Qt. See \l{Building Qt Sources} for instructions on
obtaining the Qt source code, information about Qt's prerequisites,
and guidelines on configuring and building Qt.
\section1 Copying a Qt installation to another host
It's best practice to perform a clean installation on each host that uses
Qt. However, if you need to copy a Qt installation to another host, you
need to do some extra configuring for the commercial license check to work
properly. To ensure that the commercial license check works as expected
in the copied Qt installation, carry out the steps in
\l {Copying a Qt or QA installation to another computer}.
