# Slixfeed - Syndication service of open and standard networks

Slixfeed is a news aggregation service (i.e. "bot", so called) of open and
standard telecommunication networks (OSTN);

It provides a convenient and immediate access to journals, publications, torrent
indexers, and otherwise syndicated contents.

The purpose of this service is to be ubiquitous and easy to operate with chat
software.

Slixfeed is primarily designed to XMPP, yet it is built to be extended to other
networks and protocols.

Supported networks are DeltaChat, Gemini, HTTP, and the XMPP communication
network.
