If you are not familiar with Manjaro Linux (or Arch Linux), there are a couple of things you need to understand before we go on. Arch Linux is well known in the Linux community, with a reputation of being compact, fast, flexible, and very well maintained and supported by a dedicated community.
It is also generally considered to require an experienced Linux user at least on the installation and maintenance level, because there is not a lot of time and effort invested in making user-friendly GUI tools for lots of things that experienced Linux admins consider ‘trivial’ and which can be handled from the command line interface in a very short time.
