+=======
 
-This code is based on two major, but independent, blocks:
+This is libsolv, a free package dependency solver using a satisfiability
+algorithm.
 
-1. Using a dictionary approach to store and retrieve package
-   and dependency information.
-   
-2. Using satisfiability, a well known and researched topic, for
-   resolving package dependencies.
+The code is based on two major, but independent, blocks:
 
-Google for 'sat solver' to get links to the theory behind it.
+ 1. Using a dictionary approach to store and retrieve package and
+    dependency information in a fast and space efficient manner.
 
-Requires: cmake 2.4.x
+ 2. Using satisfiability, a well known and researched topic, for
+    resolving package dependencies.
 
-mkdir build
-cd build
-cmake ..
-make
+The sat-solver code has been written to aim for the newest packages,
+record the decision tree to provide introspection, and also allows to
+provide the user with suggestions on how to deal with unsolvable
+problems. It also takes advantage of the repository storage to
+minimize memory usage.
 
-To create a package:
-make srcpackage
-see package/
