Architect is by far the best installer for Arch-based distros that I know. In my opinion “the right way” to install Manjaro. In addition to giving the user so much choises for configuring Manjaro, it also gives the user a learning experience.
I’d love to do it myself but, in fact, haven’t even yet used it before, never mind enough to maintain it. Also, while I am a web developer and know my way relatively well Around PHP and Javascript relatively well, and have done some scripting, there’s absolutely no way I’d be able to do it.
