+# MHS35-show fix for Kali Linux on Raspberry Pi 5
+# This script fixes the original LCD-show MHS35-show script which was designed
+# for Raspberry Pi OS and doesn't work properly on Kali Linux / Pi 5
+#
+# Issues fixed:
+# - raspi-config doesn't exist on Kali
+# - Boot files are in /boot/firmware/ on Pi 5, not /boot/
+# - /etc/rc.local doesn't exist on Kali (uses systemd)
+# - Various missing config files
+#
+# Usage: Run this AFTER cloning LCD-show repo
+#   git clone https://github.com/goodtft/LCD-show.git
+#   cd LCD-show
+#   curl -O https://raw.githubusercontent.com/<your-repo>/main/lcd-show-fix/MHS35-show-kali-pi5.sh
+#   chmod +x MHS35-show-kali-pi5.sh
+#   sudo ./MHS35-show-kali-pi5.sh
