The current docs are laid out more or less like this:

• short introduction
• relatively short tutorial
• reference
• how-to's/guides and some in-depth explanations

Suggesting to make the following improvements:

• add top-level headings for:
  • introduction
  • tutorial
  • reference
  • guides
  • concepts
• reorder sections according to the new ToC
• add anchors for each top-level heading
