 ### Generating the Exercises
 
-Note that the files in `exercises/` are generated from the corresponding files in `theories/`. As such, if you wish to make changes to a chapter, please make those changes to the `theories`-version of the chapter. Afterwards, the `exercises`-version can be re-generated by running `make exercises`. This requires `gawk` to be installed (which should be available on Linux, and on macOS can be installed via `brew install gawk`).
