The installers will have the native look and feel on the platform where they are run: Linux, Microsoft Windows, and Mac OS X. The Qt Installer Framework tools generate installers with a set of pages that guide the users during the installation, update, or uninstallation process. You provide the installable content and specify information about it, such as the name of the product and the installer and the text for the license agreement. You can customize the installers by adding widgets to the predefined pages or by adding whole pages to provide users with additional options. You can create scripts to add operations to the installer. You can create either \e offline or \e online installers. Offline installers contain all the installable components and do not require network connections during or after the installation. Online installers download components from a repository on a Web server. They enable users to install additional components from the server after the initial setup, as well as to receive automatic updates to content as soon as the updates are published on the server. \section1 Choosing Installer Type You can provide end users with an offline or online installer, or both, depending on your use cases. Create an offline installer to enable users to directly download the installation package on a media for installation on a computer later. You can also distribute the installation package on a CD-ROM or USB stick, for example. Create an online installer if you expect the users to have reliable network access, because it provides the users with automatic updates to installed content and easy access to all content that is added later. \section1 Promoting Updates Create online installers to be able to promote updates to end users who install your product. The easiest way to provide an update is to recreate the repository and upload it to the web server. For large repositories, you can update only the the changed components. \section1 Providing Content for Installers You can enable other content providers to add components to the installer as add-on components. The component providers must set up repositories that contain the installable components and deliver the URL that points to the repositories to end users. End users must then configure the URL in the installer. The add-on components are visible in the package manager. */
