Of course I have never understood why users new to a OS don't bother reading the Manuals and Wiki before jumping right in. but...
I myself had a bit of an issue installing Manjaro, and the embarrassing truth is I didn't even know there was a manual!
There is no mention of a manual on the download page, but also, I think my previous experiences with Linux made me kind of assume there probably wasn't one so I didn't even bother to look for one at first.
There is a manual of course - the user guide pdf in the 'more' menu (but not here?) - and it's actually really good. Please put a link to this on the download page - anyone that's downloading Manjaro is likely to need it if they're not a Linux expert so it should be in their face.
But after getting it working, I am slowly realizing that Manjaro as actually pretty incredible. The OS is super fast, super attractive and (so far) super stable. I think 'Linux on the desktop' has actually come a lot further than many people (like me) realize. Exciting times for an oldy like me!
