Nice work! You're now ready to work with DarkestHourDev! Now what?

• To launch the development version of the game, run Red Orchestra/System/DarkestHourDev.bat.
• To launch the development version of the SDK, run Red Orchestra/System/DHEd.bat.

Be sure to add shortcuts to these .bat files to your Desktop to make running the game and SDK easier.
