 =head1 DESCRIPTION
 
-Tarantool is a Lua application server fully compatible with Lua 5.1.
+Tarantool is an in-memory computing platform consisting of a database and an
+application server.
 
-It includes a mature database to persist, replicate and recover application
-state and a curated set of Lua modules for networking, I/O, messaging, data
-formats and more.
+Key features of the application server:
 
-It is designed to let developers quickly create efficient, reliable and
-powerful micro-services and backend applications for the Internet.
