 <title>Folks</title>
 
+  <p>
+    Various systems have different representations for user accounts.  For
+    example, <link xref="eds">Evolution Data Server</link> has the user's
+    list of email contacts.  <link xref="telepathy">Telepathy</link> has the user's
+    list of instant-messaging contacts.  Various web services have the user's
+    "friends".  Libfolks takes care of aggregating all these forms of contacts
+    so that you can get all the accounts that belong to one person.  This lets
+    software present lists of people in a more useful fashion, instead of
+    showing duplicated people whenever they have more than one account
+    associated to them.
+  </p>
+
+  <p>
+    In GNOME, Empathy (the instant messaging client) uses Folks to present a
+    unified view of people ("Person X has these IM accounts"), rather than
+    disparate accounts for the same person ("Person X at AIM, Person X at
+    GTalk, Person X at Yahoo! Messenger").
