+* Looks a LOT like an R package's structure (because it is one!)
+* I want to just highlight the two directories `dev` and `R`
+  + The scripts in `dev` have functions that safely do other things within the package (create scripts, add dependencies, etc.)
+  + Some scripts in this directory will create other scripts in the `R` directory
+  + The `R` directory is where all of the logic lives (your modules, custom functions, and UI/Server scripts)
