I built Vim from source and unfortunately when doing this the help system is not created (in other words you get an error if you execute :h). What is the procedure for creating the help system?
This is what I tried:
:echo $VIMRUNTIME /usr/share/vim sudo mkdir /usr/share/vim/doc sudo chmod 666 /usr/share/vim/doc :helptags $VIMRUNTIME/doc E151: No match: /usr/share/vim/doc/**
The last shown error above is where I am stuck.
