+Copyright-Free Xbox HDD Image
+=============================
+
+This repository serves as a way to document how to create an Xbox HDD image,
+mostly for use with [xemu](https://xemu.app), free of any copyrighted content.
+
+Download
+--------
+If you're in a hurry, you can [download a pre-built image here](https://github.com/xemu/xemu-hdd-image/releases).
+
+Do It Yourself
+--------------
+If you would like to create an image for yourself, containing your own files,
+you can follow these instructions. It's a bit hands-on, but if you've read this
+far you're probably okay with that. This will involve building a dummy
+dashboard, using [XboxHDM](https://www.reddit.com/r/originalxbox/wiki/xboxhdm#wiki_using_xboxhdm)
+to create a helper bootable ISO, and a QEMU VM to run the ISO and create the
+drive.
+
+You may want to start by building the dummy dashboard using
+[nxdk](https://github.com/XboxDev/nxdk). Make sure to update the Makefile with the
+path to your nxdk install. Otherwise, copy your desired dashboard and optionally
+and "E drive" files you want on the drive over to this directory.
+
+Next you'll want to run the `make-iso-*.sh` script that comes with **XboxHDM
+v1.9**. This script will create a bootable ISO image. You can run XboxHDM
+natively on Linux or Windows (not tested by me), but I chose to simply run it
+inside of a Docker container:
+
+	docker build -t xboxhdm .
+	docker run --rm -it -v ${PWD}:/work xboxhdm
+
+Create a working directory:
+
+	mkdir /tmp/xboxhdm
+	pushd /tmp/xboxhdm
+
+Unzip XboxHDM:
+
+	unzip /work/xboxhdm_v1.9.zip
+	cd xboxhdm
+
+Now copy over the dummy dash and create the empty `TDATA` and `UDATA` folders:
+
+	cp /work/xboxdash.xbe linux/C/
+	mkdir -p linux/E/TDATA linux/E/UDATA
+
+Finally, run the tool and copy over the resulting file:
+
+	./make-iso-lin.sh
+	cp linux.iso /work
+
+Now we should have a file called "linux.iso" in this directory. You could burn
+this to a CD, and run it on your PC after connecting a real HDD, but we aren't
+going to do that. Instead, to create a virtual disk image, we will use a virtual
+machine: QEMU!
+
+But before we can boot it, we need to create a virtual hard disk. Use `qemu-img`
+to create an 8G qcow2 formatted image:
+
+	qemu-img create -f qcow2 xbox_hdd.qcow2 8G
+
+Now you have an empty virtual drive. Let's fire up our virtual machine:
+
+	qemu-system-i386 \
+		-drive index=0,media=disk,file=xbox_hdd.qcow2 \
+		-drive index=1,media=cdrom,file=linux.iso
+
+Next follow the on-screen instructions, which basically go as follows:
+ - Enter 2 to boot in text mode
+ - Type xboxhd at the command prompt to start the helper script
+ - Enter 'yes' to confirm
+ - Enter 1 to "build a new Xbox HD from scratch"
+ - Continue to confirm through the warnings
+ - Confirm building a new partition table, formatting partitions, and copying files
+ - 8 to quit
+ - Type `poweroff` at the command prompt
+
+You should finally have a freshly minted, copyright-free Xbox hard disk image!
