One of the team is working on the 100+ page manual at the moment. It might not make release, but hopefully soon after.
Just to note as well, it'll be on our Steam page. We'll link to it from our Support Centre, and the Guides forum though.
Thanks, it would be great to have such manual in electronic format. By the way, you can convert to PDF, which I prefer the most, using https://pdfguru.com/djvu-to-pdf the DjVu to PDF Converter. I've been using this tool for quite a while, and it suits me perfectly since it supports a large number of formats and works online, which is great. And in my opinion, PDF is the most convenient format for working and editing.
