What's the meaning of `^=` in vimscript?

Question

What's the meaning of ^= in the following line?

set runtimepath^=~/.vim

This should be a simple one but I've searched and found nothing. Thanks for your help.

See: cursor movement - How do I navigate to topics in Vim's documentation? - Vi and Vim Stack Exchange. In this particular case you can just :help ^= in vim. — user202729, Oct 15 '21 at 01:35

Prepend runtimepath with ~/.vim,

See :h :set^=

:se[t] {option}^={value}                *:set^=*
            Multiply the {value} to a number option, or prepend
            the {value} to a string option.  When the option is a
            comma separated list, a comma is added, unless the
            value was empty.
            Also see |:set-args| above.

Actually, :help ^= is sufficient. – user202729 Oct 15 '21 at 01:34
