  sentence structure/idiom fixes (behind the hood -> under the hood)
- A polished/reordered introduction (highlighting the new special remote and
  data dissemination)
- Usage of terms that exist in the glossary, where applicable
- Referencing some other useful handbook chapters for further information, where
  applicable
- Highlighting the tutorial in the special-remotes README by introducing a
  Resources paragraph
