 # The Advanced RSS Environment
 
-The Arsse is a news aggregator server which implements multiple synchronization protocols, including [version 1.2][NCNv1] of [NextCloud News][NCN]' protocol and the [Tiny Tiny RSS][TTRSS] protocol (details below). Unlike most other aggregator servers, The Arsse does not include a Web front-end (though one is planned as a separate project), and it relies on existing protocols to maximize compatibility with existing clients.

+### Fever
+
+Unlike other protocols thus far supported by The Arsse, a reference implementation of [the Fever protocol][Fever] is no longer available: Fever was witdrawn from sale in 2016. Consequently the Arsse's implementation may not replicate all of Fever's functionality correctly. Moreover, some features have been deliberately omitted.
+
+#### Special considerations
+
+- Because of Fever's insecure authentication protocol, a Fever-specific password must be created before a user can communicate via the Fever protocol. Consult The Arsse's online help (`php arsse.php --help`) for instructions on how to set the necessary password
+- The Fever protocol does not allow for adding or modifying feeds. Another protocol or OPML importing must be used to manage feeds
+- Unlike other protocols supported by The Arsse, Fever uses "groups" (more commonly known as tags or labels) instead of folders to organize feeds. Currently OPML importing is the only means of managing groups
+
+#### Missing features
+
+- All feeds are considered "Kindling"
+- The "Hot Links" feature is not implemented; when requested, an empty array will be returned. As there is no way to classify a feed as a "Spark" in the protocol itself and no documentation exists on how link temperature was calculated, an implementation is unlikely to appear in the future
+- Favicons are not currently supported; all feeds have a simple blank image as their favicon
+
+#### Other notes
+
+- The undocumented `group_ids`, `feed_ids`, and `as=unread` parameters are all supported
+- XML output is supported, but may not behave as Fever did. JSON output is highly recommended
