I was thinking that the approach is:

• Move the current TOC in docs/readme.md into the main readme.md, at the bottom under a section called "Additional documentation", with a link in the TOC at the top to that as well.
• Copy the frontmatter and the updated readme.md into docs/readme.md

@pamelafox Arun wants all 4 building blocks to appear in the samples browser. Only a readme is ingested so each building block needs its own readme in a separate subdir. If you can think of a different way to accomplish the same goal, go for it.
