I downloaded the template and then followed the instructions here: https://books.huijzer.xyz/getting-started

I get:

Do I need to run gen() first?

[rikhuijzer]

Do I need to run gen() first?

Yes. Or create the file manually.

Interestingly enough. More people reported this error, so I should fix it.

[logankilpatrick]

Should the getting started guide have the run gen() command section first then?
