+Learning how to use the Jetson NX
+
+## Remote Python Interpreter
+Since this needs to run on the Jetson Xavier NX we have to ensure that the remote python interpreter is set.
+
+```
+sudo apt update
+sudo apt install python3.8-dev python3.8-venv
+```
+
+To use the GPIO you need the [Jetson.GPIO] library installed, create a gpio group, and apply the custom udev rules.
+
+```
+python3.8 -m pip install Jetson.GPIO
+```
+
+This installs the package in the user home .local folder. We need to know this location to copy the [udev rules].
+
+```
+sudo cp ~/.local/lib/python3.8/site-packages/Jetson/GPIO/99-gpio.rules /etc/udev/rules.d/
+sudo udevadm control --reload-rules && sudo udevadm trigger
+```
+
+To start playing with GPIO you can reference the samples at https://github.com/NVIDIA/jetson-gpio. A detailed GPIO pinout 
+can be found [here at JetsonHacks](https://www.jetsonhacks.com/nvidia-jetson-xavier-nx-gpio-header-pinout/).
