-This Linux Deployment Tool for Qt, `linuxdeployqt`, takes an application as input and makes it self-contained by copying in the Qt libraries and plugins that the application uses into a bundle. This can optionally be put into an [AppImage](http://appimage.org/), and, using [fpm](https://github.com/probonopd/linuxdeployqt/issues/9), into cross-distro deb and rpm packages.
+This Linux Deployment Tool, `linuxdeployqt`, takes an application as input and makes it self-contained by copying in the resources that the application uses (like libraries, graphics, and plugins) into a bundle. The resulting bundle can be distributed as an AppDir or as an [AppImage](https://appimage.org/) to users, or can be put into cross-distribution packages. It can be used as part of the build process to deploy applications written in C, C++, and other compiled languages with systems like `CMake`, `qmake`, and `make`. When used on Qt-based applications, it can bundle a specific minimal subset of Qt required to run the application.

 ## Differences to macdeployqt
 This tool is conceptually based on the [Mac Deployment Tool](http://doc.qt.io/qt-5/osx-deployment.html), `macdeployqt` in the tools applications of the Qt Toolkit, but has been changed to a slightly different logic and other tools needed for Linux.
