Phoebe is a Gemini-first WikiEngine by Alex Schroeder. It has a wiki space on the TransjovianCouncil, at Phoebe.
“Gemini-first” means that some functionality is only available via Gemini, and that functionality that would be available only via HTML is not available at all. That is to say: the HTML and HTTP side of it is very, very simple – and intentionally so.
