How to install PlatformIO remote agent on Raspberry Pi

This is from the Super Quick installation procedure from the official PlatformIO documentation:

python3 -c "$(curl -fsSL https://raw.githubusercontent.com/platformio/platformio/master/scripts/get-platformio.py)"
sudo apt -y install rustc libffi-dev
echo "export PATH=\$PATH:/home/${USER}/.platformio/penv/bin" >> ~/.profile

Run it as user (whatever user you want to use PlatformIO as - by default, this is the pi user) and not as root!

After running these commands, log out and log back in againin order for the changes to the PATH environment variable to take effect.

After that, run

pio remote agent start

to complete the installation procedure. This will take quite some time.

After logging in, you can use pio from the shell:

$ pio
