+# Install Dietpi on HackberrPi_CM5
+
+``Step 1`` Download the Raspberry pi 5 DietPi Image from here https://dietpi.com/#downloadinfo
+
+``Step 2`` Flash the downloaded image into a TF card
+
+``Step 3`` Copy the following content into the config.txt and override
+
+``Step 4`` Insert the TF card into the HackberryPi_CM5 and power it on, wait a few seconds and you can see it booting

+#-------Display---------
+# Max allocated framebuffers: Set to "0" in headless mode to reduce memory usage
+# - Defaults to "2" on RPi4 and "1" on earlier RPi models
+#max_framebuffers=0
+
+# If you get no picture, set the following to "1" to apply most compatible HDMI settings.
+#hdmi_safe=1
+
+# Uncomment to adjust the HDMI signal strength if you have interferences, blanking, or no display.
+# - Ranges from "0" to "11", use values above "7" only if required, e.g. with very long HDMI cable.
+# - Default on first RPi1 A/B is "2", else "5", on RPi4 this setting is ignored.
+#config_hdmi_boost=5
+
+# Uncomment if HDMI display is not detected and composite is being outputted.
+#hdmi_force_hotplug=1
+
+# Uncomment to disable HDMI even if plugged, e.g. to force composite output.
+#hdmi_ignore_hotplug=1
+
+# Uncomment to force a console size. By default it will be display's size minus overscan.
+#framebuffer_width=1280
+#framebuffer_height=720

+# Uncomment to enable SDTV/composite output on RPi4. This has no effect on previous RPi models.

+#sdtv_mode=0
+
+# Uncomment to force a specific HDMI mode (this will force VGA).
+#hdmi_group=1
+#hdmi_mode=1
+
+# Uncomment to force an HDMI mode rather than DVI. This enables HDMI audio in DMT modes.
+#hdmi_drive=2
+
+# Set "hdmi_blanking=1" to allow the display going into standby after 10 minutes without input.
+# With default value "0", the display shows a blank screen instead, but will not go into standby.
+# NB: Some legacy OpenMAX applications (OMXPlayer) cannot wake screens from real standby.
+#hdmi_blanking=1
+
+# Set to "1" if your display has a black border of unused pixels visible.

+# Uncomment the following to adjust overscan.
+# Use positive numbers if console goes off screen, and negative if there is too much border.
