What is "it" though? It's hard to figure out from any of the About page, Design, or the README [1, 2, 3].
Only when getting to the Architecture [4] section much later in the docs, it starts mentioning ActivityPub, but still no useful description of the project - "an unusual piece of software" is the only provided bit. Is it a framework, a new protocol, a network? Looks like the former - an application to write ActivityPub based software, but I'm only 50% sure.
