There's a very good EPUB editor called Sigil https://www.mobileread.com/forums/forumdisplay.php?f=165

The focus of manuals of tools is typically on functionality.

I'm looking for an article with basic thoughts with the focus on minimalistic code.
I think there are only few user who like the radical wish to have an epub without any "styles", just pure semantic.

When I understand
http://idpf.org/epub/30/spec/epub30-overview.html
correctly, there are 4 obligatory files of a minimalistic epub:
/META-INF/container.xml
/mimetype
/directory.opf
/content.xhtml

And 2 more files for the TOC and the cover:
/cover.jpg
/toc.ncx
