 ## Install SolusOS with raid0 /home device
 
+I don't know if this is correct or not, but it's working for me.
+First, torrent the latest iso and write it to a thumb drive with ddrescue
+
 ```bash
-ddrecue -D --force Solus-1.2.1.iso /dev/sdX
-```
+ddrescue -D --force Solus-1.2.1.iso /dev/sdX
+```
+
+On my machine you can write the thumb drive using USB 3, but you have to
+afterwards move the thumb drive over to a USB 2 port to uefi-boot. At boot
+time on Asus X99 mobo, tap the f8 key for boot device menu, and select uefi-usb.
+
+The SolusOS installer will insist on formatting the / partition, so back that up,
+and then mdadm is not installed so you will have to install that.
+
+```bash
+eopkg install mdadm
+```
+
+If you need to create your raid device, the [Arch Wiki](https://wiki.archlinux.org/index.php/RAID)
+is a great resource, but you'll at least need to assemble the raid.
+
+```bash
+mdadm --assemble --scan
+```
+
+Now you can run the installer gui application, and select the raid device as your home partition. But
+there is some addition configuration you'll need to do via chroot. Mount your / device and chroot into
+it.
+
+```bash
+mount /dev/sdxY /mnt
+```
+
+or in case of nvme / device
+
+```bash
+mount /dev/nvme0n1p1 /mnt # (or similar)
+```
+
+and then perform chroot
+
+```bash
+chroot /mnt
+```
+and then install and set up mdadm
+
+```bash
+eopkg install mdadm
+mdadm --detail --scan >> /etc/mdadm.conf
+```
+
+and then you might want to adjust fstab
+
+```text
+# UUID=0421c6.......dd6ecc7     /home   ext4    discard,rw,relatime,errors=remount-ro   0      2
+UUID=0421c6.......dd6ecc7     /home   ext4    rw,relatime,stripe=256,data=ordered   0      2
+```
+
+There doesn't seem to be an `update-initramfs` commmand available, so not sure if raid / device is possible.
