 # Configuration
 To Install LinuxCNC_ArduinoConnector.ino on your Arduino first work through the settings in the beginning of the file.
 The Settings are commented in the file.
 
 To test you Arduino you can connect to it after flashing with the Arduino IDE. Set your Baudrate to 115200. 
-In the Beginning the ARduino will Spam ```E0:0``` to the console. This is used to establish connection. 
+In the Beginning the Arduino will Spam ```E0:0``` to the console. This is used to establish connection. 
 Just return ```E0:0``` to it. You can now communicate with the Arduino. Further info is in the Chapter [Serial Communication](#serial-communication-over-usb)
