Huh, what?
Did you read his “solution” though?
Anyway, how will you learn if you won’t even try? Sometimes you just have to spend few hours (or days) before you manage to make something work for the first time. (Pihole install is pretty straightforward though.)
It won’t get any easier as with a wiki. So giving guidance in this case is usually giving you a link of some wiki. 
And from your side it makes sense you first try making it work. And only after you did A, B and C and can’t do D, you open a thread where you write in detail what you did and where you’re stuck.
