How to update books?

[mouse07410]

This is a great tool - but the books versions it contains are 6 years outdated.

It would be good if there were some guidance on how to update the book content and, e.g., produce an eBook of the current (2022-12-xx) version of TRPL, rather than that of 2016.

It could be as simple as just replacing all the .md files with the new ones pulled from GitHub - but it would be best if the maintainer of this tool described the process explicitly.

And thanks again for this useful tool!
