What blocks are included? Request to improve minimal documentation

The blocks currently include:

1. Children: list of child pages for the current page
2. Navigation: Replicates the navigation links found at the bottom of the page.
3. Table of Contents: Book's table of contents that also includes a link to
the top page.
4. Edit: Includes a combination of navigation, table of contents and edit
links.

It would be great indeed if this could be shown on https://www.drupal.org/project/book_blocks →

Minimal changes made to documentation and hook_help.
