Update

When you install the updates, the system, piRa1n, piRa1n-web (if installed) and checkra1n are updated

Update from the version 3 and above

If you've used piRa1n-OS (the quick installer) or you've installed piRa1n-web

1. Type the hostname of your Pi (something like raspberrypi.local) or its IP address in a browser.
2. If a new update is available, you will see a button which asks you to update. Please don't shut down the Pi until the updates are installed.

If you've used the manual installer and piRa1n-web isn't installed

Run this command: sudo /home/pi/piRa1n/piRa1n -u or curl -sk 'https://raw.githubusercontent.com/raspberryenvoie/piRa1n/master/update.sh' | sudo bash

Update from the version 1.x or 2.x of piRa1n

Follow all the installation steps for your board.
