 # Vibe.d web framework
 
 [Vibe.d](http://vibed.org) is a very powerful web
-framework which this tour for example has been written
-with. Here are some highlights of vibe.d:
+framework which, for example, underlies this D language tour website.
+Here are some of vibe.d's highlights:
 
 * Based on a fiber based approach for *asynchronous I/O*
-  vibe.d allows to write high-performance HTTP(S) web servers
-  and web services. Write code which looks synchronous
-  but actually does the ugly asynchronous handling
-  of thousands of connections in the background
-  for you! See the next section for a thorough
-  example.
-* An easy to use JSON and web interface generator
-* Out-of-the-box
-  support for Redis and MongoDB make it easy to
-  write backend systems that have a good performance
-* Generic TCP or UDP clients and servers can be
-  written as well using this framework
