 ===== Software Setup =====
-[[http://hg.protofusion.org/ZonCoffee/archive/486905a58273.zip|Download the ZonCoffee Arduino sketch and libraries]]
+To get started, [[http://hg.protofusion.org/ZonCoffee/archive/486905a58273.zip|download the ZonCoffee Arduino sketch and libraries]]
+Your ZonCoffee board comes pre-loaded with the latest firmware. However, you can flash your own custom firmware
+==== Arduino IDE ====
+Download the latest [[http://arduino.cc/|Arduino IDE]] and make sure that the selected board is Arduino Leonardo. The IDE should function as if the ZonCoffee was a normal Arduino Leonardo.
+Note: In that zip file, all libraries in the "lib" folder need to be installed to your Arduino IDE. If you haven't done this before, you just need to copy and paste all subfolders of the "lib" directory into the "libraries" folder of your Arduino installation.

 ==== LCD support ====

 The firmware comes pre-configured for the HD44780 parallel LCD display. To use a SparkFun serial LCD, you will need to change a couple configuration options:
-In the Arduino sketch, browse to options.h
+In the Arduino sketch, browse to ''options.h''
 //#define LCDSF      // Use SparkFun serial lcd

 Uncomment the LCDSF line and comment out the LCDHD line. Now your SparkFun LCD should work properly.
-==== Libraries ====
+**There seems to be a bug in the Arduino IDE when switching between LCDs. If you change the selected display in ''options.h'' and get a ton of compilation errors, change the order of these two blocks in zoncoffee.ino (for example):**

+Change this:
+// Setup LCD
+#ifdef LCDHD
+   #include <LiquidCrystal.h>
+   LiquidCrystal lcd(A5,A4,A3,A2,A1,A0);
+#endif
+
+#ifdef LCDSF
+   #include <SLCD.h>
+   SLCD sflcd = SLCD(LCDROWS, LCDCOLS);
+#endif
+To this:
+// Setup LCD
+#ifdef LCDSF
+   #include <SLCD.h>
+   SLCD sflcd = SLCD(LCDROWS, LCDCOLS);
+#endif
+#ifdef LCDHD
+   #include <LiquidCrystal.h>
+   LiquidCrystal lcd(A5,A4,A3,A2,A1,A0);
+#endif
+
+...or the other way around.
