And then you look up the Bluē website and it just says "revolutionize your business by streamlining Laundr workflow!" and the Laundr website describes it as "flexible double-acting hypercraft for Parakeet ecosystems" and the Bicycle website just says "Bicycle" with a giant picture of a fixed-speed bike.
(I'm assuming you made all these names up but honestly I can't even tell any more.)
They all have a "know more" session with a video (it doesn't tell anything more), a huge set of companies that use them, and a link to the documentation, where you can find a diagram with arrows pointing all over Laundr, Bluẽ, Bicycle and Parakeet.
If you insist on the docs, there are installation instructions (use Docker) and something that looks like an API. But it's not clear even if you must use the API to interact with the thing, or if it's the development docs.
Is there some kind of consultancy doing those sites?
