Not sure it is fair to say "Google just released Lullaby" in the submission title:

1. The README.md file indicates "Disclaimer: This is not an official Google product."

2. This site's guidelines prohibit editorializing of titles.

A more appropriate title would perhaps just be "Lullaby: C++ libraries to help teams develop VR and AR experiences." This uses only the text on the actual linked page.

There are many repositories under the "google" organization on GitHub. A great number of them are not "Google products" but just projects that Google employees work on.

"Used by multiple teams across Google incl: VR Home, Play Store, YouTube, Play Movies, and Earth." is also there in README.md. But yes, it's not a Google product but it's Google's library.
