Mellow is an elegant, easy-to-use, modern operating system intended to provide a familiar computing environment combining ideas of Window and Unix philosophies.
The primary goal of Mellow is to remove the perceived divide between the accessibility and familiarity of Windows and the power and flexibility of Unix/Linux.
Mellow also acts as a spiritual successer to my other operating system - Miyabi. The reason can be found here.
More information about Mellow can be found at docs in the project's root directory.
