Ministro is a service that lets you install and manage the free versions of Qt libraries, which are used by many apps and games. It can also provide you with the source code of the libraries, and you can build them yourself.

The service is used as a bridge between the apps and the libraries. The source code of the libraries is available under the GNU Lesser General Public License (LGPL), and they are distributed in the free version and the commercial version.

For more information about how the service works, please check the documentation that is available on the website.

The source code of the application is also available under the GNU General Public License (GPL).
