Its been a while since we've been seeing ICOs happening.

Are there some guidelines one can come up with to reach out to the community and get them to participate in the ICO?

The most solid compilation that i have got to date is this :

But this doesn't talk about how to make sure you are able to reach out to the potential investors for your ICO.

I know this is a very vague quesetion, but, any leads on this?
