 Let's start with a really simple example. Say you have written a function to calculate factorials and now you want to test it. To keep things simple we'll put everything in a single file.
 
 ```c++
-    #include "catch_default_main.hpp" // This brings in a default implementation for main()
+    #include "catch_with_main.hpp" // This brings in a default implementation for main()
 
     unsigned int Factorial( unsigned int number )
