While I read through the docs I saw the section about translation:

https://squidfunk.github.io/mkdocs-material/setup/changing-the-language/#site-language-selector

While they describe how to configure it in mkdocs.yml I am missing some information about directory structure.

I now I could use i18n plugin, but we are not planning to support asian language.

What I have in mind is something like this:

.
├── docs
│   ├── de
│   │   ├── special
│   │   │   └── page.md
│   │   └── index.md
│   ├── en
│   │   ├── special
│   │   │   └── page.md
│   │   └── index.md
│   └── stylesheets
│       └── extra.css
└── mkdocs.yml

But this leads always to 404 page and the navigation still shows “De” and “En” instead of “index” and “special”.

What do I need to change and why is the documentation missing out?
