Can find here in IFarchive or in this repository. I'll upgrade the readthedocs version from Gitlab. Follow build from here.
Web version of Jim AIkin's handbook about Inform7, the natural programming language for IF (interactive fiction).
Github repository contains markdown files of every section of the handbook and a web version hosted with github pages. To create the structure and html files, I've used gitbook. The same file are used to create a version on Readthedocs using Mkdocs.
