I just installed Geonode via quick installer, which seems pretty convenient. After that, I noticed the "Theme" option from "Django Administration" was no longer there, which was available if Geonode is installed by dev mode.
How do I customize Geonode?
I saw there is another Q&A here: Customize GeoNode after a quick install
But what confused me in the answer is that you need to change "/home/geonode/geonode/geonode/templates/site_index.html", but this path does not exist if quicker installation method is used. So I became totally lost and couldn't not figure it out anything.
