 In order to tinker with the code, you'll more than likely need to use the debugging features of your IDE. To make them the easiest to use, you should switch to the Debug configuration - this provides the highest level of information while debugging, for the price of the executable being 2 - 10 times slower. Go to menu Build -> Configuration Manager, and in the opened dialog, change the top left combo box (Active solution configuration) to Debug. Close the dialog and build the solution. The resulting executable is called `Cuberite_debug.exe` in the `Server` folder.

 Follow the instructions in [COMPILING.md](https://github.com/cuberite/cuberite/blob/master/COMPILING.md). You probably want to build in debug mode (when you're developing) for console alerts and debugging capability, even though it's much slower for everyday use.
