Change icon and text homepage

Good day

I would like to ask. I would need to change the default image and text on the main page.

The link points to /opt/gogs/templates/home.tmpl
Image link to /opt/gogs/public/img/gogs-hero.png

when I change the text and the image, nothing happens. As the file changes, everything remains in the default state on the web page.

Debian 10 / GOGS 0.11.91

Thank you


ps: Customising the default homepage?
this procedure does not work for me.

Here you go
