what does this mean??

[wisdomlight]

after my first guix pull
this came:

> hint: After setting `PATH', run `hash guix' to make sure your shell refers to
> `/home/sherab/.config/guix/current/bin/guix'.

what PATH do i need to set?
How?
How do I make sure the shell refers to 
´/home/sherab/.config/guix/current/bin/guix  ´  ??

Thanks

Will become a mere recollection
For what has past will not be seen again
