I'm definitely not a fan of including sudo, I think it gets people in the habit of using it without knowing what it is, and it's not part of the command -- if you need to run X as root, the command is X; sudo X is just one way to run it as root. I would prefer using # to explicitly saying as root (I probably should've used # instead of $ on this questionthis question), but you're right that some people might not realize what it means, so I suppose something like this will work:
To solve your problem, run the following as rootas root:
# ./do-stuff-as-root
