Document reading mode for web authors
Lastly, I’d also like to ask that you add documentation on how body text, titles, author names, dates, etc. are selected; and how web authors/developers can troubleshoot their compatibility with reading mode. Any web author who want to make sure their website supports reading mode in Epiphany should have the necessary documentation available to give Epiphany users a good experience. E.g. something like https://wiki.gnome.org/Apps/Web/Docs/Applications but for reading mode.
Update. I’ve since tried to document reading mode for all browsers.
