How did you communicate value?

There's a problem, but you have a solution. How did you communicate the solution to potential users?

Hi IH, I am struggling to explain what problem my product solves. Mainly because there are multiple use cases for the product. I am not sure what my value proposition should be.

I can either:

• Tell people about the basic use case (but I'm worried that the value of the
  product will be lost)
• Tell people about the basic use case and slowly introduce the bigger picture (but how?)
  The basic use case isn't a pain point. Therefore I'm worried no one would care if that's the initial selling point.

Anyways - I would love to hear what you did to communicate value
and any feedback is much appreciated.
