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. \image qtinstallercomponents.webp \section1 Using \QMT Once Qt is installed, you can use \QMT under 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}. \image maintenancetool.webp \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}. */
