+  The existence of this file makes sources buildable with the Arduino IDE.
+
+  While Teacup can be built and uploaded using Arduino IDE, please consider
+  using Configtool for this task. Configtool not only allows printer
+  configuration in a GUI, it also builds smaller and faster binaries. Build
+  and upload functions can be found in the main menu there.
