+#cloud-config
+# Example: create user (pi) with password, enable SSH, install KDE Plasma with touch options,
+# set KDE as default GUI, and deploy Chromium kiosk autostart.
+# Uses start-chromium.sh and chromium-kiosk.desktop from this project (emmc-provisioning/cloud-init/).
+#
+# 1. Generate a password hash on a Linux host:
+#      mkpasswd -m sha-512 'YourPassword'
+#    or: openssl passwd -6 'YourPassword'
+#    Paste the full output (e.g. $6$...) into the passwd: line below.
+# 2. To use a different username than "pi", replace every "pi" in this file.
+# 3. To change the kiosk URL, edit the --app=... line in the start-chromium.sh content below.
