Agree with @jibal! Read the "Learn Nim in Y minutes" for an overview of the 
language. Read "Nim tutorial I and II". Peruse the documentation for an 
overview of the library capabilities. And as you do, try writing and running 
some Nim code in the process. Rosetta is a good place for exercises as you've 
already discovered. If you hit a road block, ask some questions here and on 
Stackoverflow. One step at a time. You will not need C for a while so I won't 
recommend it right away.
