+## Advantages
+
+In order to solve your puzzle, you might need the debugger from time to time,
+especially as the puzzles become harder.
+
+This template is built around test projects, in order to take advatage of the
+debugging possibilities and TDD if you want to.

 ## Usage
 
 This template exposes two classes: a `Solver` and a `TestEngine`.
