 Avocado Test Framework
 ======================
 
-Avocado is an experimental test framework that is built on the experience
-accumulated with `autotest <http://autotest.github.io/>`__.
-It aims to implement the good concepts that make autotest a good test
-framework:
+Avocado is a test framework that is built on the experience accumulated with
+`autotest <http://autotest.github.io/>`__, while improving on its weaknesses
+and shortcomings.
 
-* Extensive test API.
-* Rich logging and system info collecting facilities all executed transparently.
-* Loosely coupled components that can help to fully automate testing on a grid
-  of test machines.
+The main goal of the Avocado project is to provide a set of smart tools for
+automated testing and continuous integration. Among them, we can highlight:
 
-While trying to streamline it and make it easier, more approachable for the
-single developer looking to improve testing for his/her project.
+- A powerful test runner;
+- A multiplexer that allows tests to be run with different sets of variables;
+- Test APIs for test writers;
+- A database for results, with a web interface;
+- A scheduler for setting up a test grid.
