I enjoyed reading the first few chapters, but wanted a PDF as well. I run browserless.io, so threw a quick script together to PDF-ify this. Gist is here: https://gist.github.com/joelgriffith/0e6a2a774317e845206ca8d....

You can pretty much just create a free plan and run this in our debugger, which will compile the chapters and return PDF. Pretty fun little challenge.
