+To be productive, it takes time to learn about the micro-architecture, *Rocket-chip* components, *Chisel* (maybe *Firrtl*), *Scala*, and the build system.

 Instead of focusing solely on those topics, this section hopes to show how they all fit together by giving a high level of the entire build process.
 Put in more specific terms: How do you get from *Scala*/*Chisel* to Verilog? [2]_
