 To install the module, use your terminal to:
 1. Navigate to your MagicMirror's modules folder. If you are using the default installation directory, use the command:<br />`cd ~/MagicMirror/modules`
 2. Copy the module to your computer by executing the following command:<br />`git clone https://github.com/glitch452/MMM-LocalTemperature.git`

 The included `DHT` program is something I pieced together based on code from [dht22 by nebulx29](https://github.com/nebulx29/dht22) and the [Python DHT Sensor Library by Adafruit](https://github.com/adafruit/Adafruit_Python_DHT).
 
+Verify that the correct pin is defined in `DHT.c`. Make sure the WiringPi pin number is set (you can find the WiringPi pin number for the GPIO pin [here](https://pinout.xyz/pinout/wiringpi)).
+
 If you would like to customize the `DHT` program, you can edit the file `DHT.c` with your favorite editor, then re-compile it using the following command: `cc -Wall DHT.c -o DHT -lwiringPi`
