After some mind-boggling time on the command line, I managed to get the generation process up and running. Now I can simply use markdown to write the book chapters and let the stuff generate with pandoc/kindlegen to get epub and mobi files. Much easier to preview and check how the layout works in e-reader formats.
Also I updated the website https://remoteagility.com with a newsletter signup option and share buttons for Facebook/Twitter.
Now it's just me and the content ;-)
So long - Kai
