+# This configuration can be used to run any distribution on a any x86-64 machine.
+# As example is used CentOS distribution but can be applied to others also.
+#
+# Install CentOS using classic partition scheme (not use LVM) with minimal
+# 2 partitons /boot/efi and /root. For root please choose only necessary size
+# e.g. 10G (or desired size).
+#
+# This has been tested on images generated with the following command:
+#
+# Boot live USB and copy the data from internal storage (hdd, eMMC) e.g. for eMMC:
+#
+# 	dd if=/dev/mmcblk0 of=/media/usb/centos.img bs=1M count=10000 status=progress
+#
+# Before running mender-convert we need to fix GPT partition table (as we didn't copy
+# whole hdd). Run following command to fix GPT partition table on copied image:
+#
+#	sgdisk -e /media/usb/centos.img
+#
+# Converted with the following command:
+#
+#	MENDER_ARTIFACT_NAME=release-1 ./docker-mender-convert \
+#		--disk-image input/centos.img \
+#		--config configs/centos_x86-64_hdd_config \
+#		--overlay rootfs_overlay_demo/
+#
+# and image must be then copied back after conversion to internal storage (when booted again from live USB) e.g. for hdd:
+#
+#	zcat /media/usb/centos-x86_64-mender.img.gz | sudo dd of=/dev/sda bs=1M status=progress
