Follow the instructions! It's easy to use PuTTY to paste the script into the Pi, -but after that, it's all drag and drop. You can type/paste the script directly into the Pi terminal if you want to connect the Pi to a monitor. Be advised to get all your UPDATES/UPGRADES and be sure to set all your Pi configuration defaults (location, user, password, time, memory expantion, language, wifi default) before you launch your Cayenne loader,. Have fun!
