Mint OS is a Linux distribution based on Debian, made of primarily open source packages. It's stated goal is to provide a friendly desktop environment, with a support community for new users.
Linux Mint is a computer operating system based on the Ubuntu Linux distro, which in turn is based on Debian. Mint provides an up-to-date, stable operating system for the average user, with a strong focus on usability and ease of installation. It is recognized for being user-friendly, particularly for users with no previous experience in Linux.
Linux Mint is composed of many software packages, of which the vast majority are distributed under a free software license (also known as open source).
The main license used is the GNU General Public License (GNU GPL) which, along with the GNU Lesser General Public License (GNU LGPL), explicitly declares that users are free to run, copy, distribute, study, change, develop and improve the software.
Linux Mint is funded by its community of users.
Individual users and companies using the operating system act as donors, sponsors and partners of the distribution.
The financial support from the community and advertising on the website helps to keep Linux Mint free and open source.
