github.com/scripting/rss.chat is organized the way the product is: a client folder and a server folder, each with its own code and docs, and a new top-level examples folder for complete apps built on the APIs. The first example is threadwalker, a small Node app that walks a whole conversation using nothing but the RSS feeds — no API calls, no account — and prints it as an indented outline.
These docs moved too. The basics doc is now the readme of client/docs, so it's the first thing you see when you browse the folder, and the firehose documentation is a section inside it — one document, because the whole site is for developers.
