>The output if full of blog posts that I never encountered while searching on Google
That's strange. I searched the same term (as well as let archive.is do it[1][2]) and results are similar. A workshop paper available on GitHub, a Springer Link reference entry, and a GitHub project. Indeed Hello has a single blog post whereas Google has lecture notes but there isn't a difference in content since the blog post is written in same style (essentially being a tl;dr version of the paper that introduces the methods).
