Hi. Sorry I don't have a good answer for you, but check sbt docs, it's pretty comprehenful, but it's not best.

Your best bet is to visit opensource projects and look into their build.sbt's, how they do things -they're usually not big enterprise projects and you can quickly 'get' how they setup what.

Always feel free to visir /r/scala and ask sbt-related question there, there is active community happy to answer both sbt/scala/fp related questions.
