chore: update Docus

[Tahul]

Hey Daniel 😄

I updated the docs for this package using latest Docus.

Just two comments:

• The filesystem-based routing currently does not allow to nest "Introduction" the exact same way you did on the currently deployed site. "Introduction" is so at the first level of navigation, on top, as it is in filesystem.
• Node version for deployment needs to be set >14, this deployment might be breaking even if it works with correct Node version.

If anything else is needed, please let me know! 😄
