As i started with manjaro, i skimmed through the wiki and then looked at the forum tutorials. The wiki is nowadays pretty much useless in the everyday life of the average user, just like the pdf manual before that. It is just not maintained. The forum has more information, BUT the search engine is terrible, so one is actually better off using an external search engine like google or duckduckgo with site:… tag.
3 notable exceptions, that still make the wiki important, those pages are up to date and not covered in the forum and often linked, so the otherwise useless wiki has to stay because of these 3 tutorials (until someone migrates them to the forum):
- the pacman-mirrors
Pacman-mirrors - Manjaro - problems with pacman and errors about keys
https://wiki.manjaro.org/index.php/Pacman_troubleshooting/#Errors_about_Keys - grub restore
GRUB/Restore the GRUB Bootloader - Manjaro
