Ubuntu Muslim Edition
UbuntuME stands for Ubuntu Muslim Edition. Ubuntu Muslim Edition is a free, open source operating system based on the popular Ubuntu Linux.
Ubuntu Muslim Edition is a set of packages that customizes the Ubuntu distro by installing islamic software (prayer times, Quran study tool, web content filtering tool etc.) and by changing its design.
Ubuntu is a great distro, easy to use for a novice user, with the most-used Office, Internet, Graphics and Video applications already installed but we think that for Muslim users it would be great to have “out of the box” Islamic software and tools installed as well.
Follow these instructions.
