Customizing Saturn theme

I’m trying to customize the Saturn theme text across the front that says “HELLO, I’M SATURN. I’M PROUD TO BE A PART OF MILKY WAY”

The only instance of this text appears to be in the:

cache/complied/config/master-localhost/php & cache/complied/files/2341(randomnumbers)23412312.yaml.php

each time I edit the text, then clear the cache the old text returns.

You should learn about how grav really works.

Look at user/config/site.yaml …
