-# dcu
-Dasharo Configuration Utility
+# dcu - Dasharo Configuration Utility
+
+## Introduction
+
+The Dasharo Configuration Utility is a script designed to facilitate tasks such
+as customizing the boot logo and setting unique UUIDs or Serial Numbers for
+SMBIOS. This readme provides only the most basic information. For details
+please refer to [our guide](https://docs.dasharo.com/guides/image-customization/)
+.
+
+## Prerequisites
+
+Following packages must be installed:
+
+* `imagemagick` (for `convert` command)
+* `util-linux` (for `uuidparse` command)
+* [coreboot's
+cbfstool](https://github.com/coreboot/coreboot/tree/master/util/cbfstool)
+
+## Usage
+
+```txt
+Usage: dcu OPTIONS coreboot.rom
+
+  coreboot.rom  - Dasharo coreboot file to modify
+
+  OPTIONS:
+    -u | --uuid <UUID>              - UUID in RFC4122 format to be set in SMBIOS type 1 structure
+    -s | --serial-number <SERIAL>   - Serial number to be set in SMBIOS type 1 and type 2 structure
+    -l | --logo <LOGO>              - Custom logo in BMP/PNG/JPG/SVG format to be displayed on boot
+
+  Examples:
+    ./dcu -u 96bcfa1a-42b4-6717-a44c-d8bbc18cbea4 -s D07229051 -l ~/logo.svg coreboot.rom
+
+    ./dcu -u `dmidecode -s system-uuid` -s `dmidecode -s baseboard-serial-number` coreboot.rom
+      Above command will obtain the current SMBIOS UUID and Serial Number
+      from the system and patch the coreboot binary.
+```
