+### Reasons for creating of FASI
+
+The main reasons for the realization of FASI are:
+
+- Add interactive capabilities, as well as vCard information;
+- Create rapport with the viewers, by displaying vCard information, such as Full
+  Name and Description or Note;
+- Charm our "normie" friends, so called, by displaying an attractive contact
+  HTML page, which they can also utilize;
+- Utilize an invitation page, with XMPP capabilities, regardless to the software
+  that powers an XMPP server;
+- Realize that HTTP is obsolete and should be treated as an optional publishing
+  mean, because anything that HTTP offers, is already possible with XMPP, since
+  a couple of decades ago.
+
+### Special features
+
+- Fetch vCards and photos;
+- Indicate of available conferences, nodes and services;
+- Retrieve number of conferences, nodes, participants, node items and services;
+- Preview recent conference messages;
+- View journal articles (i.e. PubSub node items that are published as Atom Over
+  XMPP).
+
+### Byproduct
+
+- Browse services;
+- Explore JID and node items.
+
+### Other features
+
+- Customization for specific brands (e.g. monocles chat);
+- Dynamic background in accordance to the photo colors.
