How to mount MTP devices on Arch Linux

It comes down to this:

yay -S jmtpfs
mkdir ~/mnt
jmtpfs ~/mnt

A word of caution

I had the audacity to try and copy my whole music collection (about 100GB) with this method, which at some point stopped because an ‘general IO error’. Now I have a folder in my home directory which I can not delete, move, copy or anything else.
