As soon as that was performed, all that was left to do was begin utilizing FreshRSS.
Whereas the preliminary DietPi setup was self-explanatory, I made a mistake in not trying on the DietPi documentation. I did not perceive the “software program password” idea at first. I used to be confused why FreshRSS internet interface was asking me to log in with a username and password despite the fact that I hadn’t created one but.
