Manjaro Linux : Tips and Tricks (ARCH Linux under the hood)

Manjaro Linux : Tips and Tricks

We have been using [Manjaro linux][2] for past year and have been happy with its perfomance. Though we don't use te [AUR][1] (Arch User Repository, since many are not supported into Manjaro.

The best part is even with bad / dumb users like myself, IT-DOES-NOT-BREAK. So, we very much recommend [Manjaro][2].

It seriously worked much better than Ubuntu. We might not be able to have all the boat load of software & support like Debian, but we are happy.
