Following this guide and changing the dock server for Raspberry
I was able to create an account in nextcloud like in 10:38 of the Tecno Dad Life's guide
but I am able to login in Nexcloud! and it look normal but with the generic folder how to attach my Data
further more I do not know whereto enter credential for MySQL/MariadDB
Where inside the Nextcloud GUI can I add those parameters?
Or even thu CLI how to fix it without starting from scratch?
