-The YaCy search engine software provides results from a network of independent peers,
-instead of a central server. It is a distributed network where no single entity decides
-what to list or order it appears in.
 
-User privacy is central to YaCy, and it runs on each user's computer, where search terms are

-- Comprehensive concept to anonymize the users' index
+Each YaCy peer can be part of a large search network where search indexes can be
+exchanged with other YaCy installation over a built-in peer-to-peer network protocol.
