Allow custom content on homepage via meta-data (front-matter)

[froschdesign]

The content of the homepage is created automatically.
The site_name and the site_description from the MkDocs configuration file are used, the links of the support section are hardcoded.

But custom content can also be added. This can be configured via a configuration entry in the mkdocs.yml file but it would be more intuitive to insert this directly into the related file.

Current Usage

mkdocs.yml

extra:
    show_special_homepage: true
