If you don't want to setup a global environnment, you can also setup one just for this app by sourcing prepare-devenv.sh with the right target (s or x).

install prerequisite and switch to a Nano X dev-env:

sudo apt install python3-venv python3-dev libudev-dev libusb-1.0-0-dev

# (x or s, depending on your device)
source prepare-devenv.sh x 

Compile and load the app onto the device:

make load

Refresh the repo (required after Makefile edits):

make clean

Remove the app from the device:

make delete
