+## How to setup this machine.
+
+This machine cannot be setup the same way as other machines are setup. Meaning that `clan machine install` won't work. Because of `disko` issue. So, below is how the machine is setup.
+
+1. Build an image to flash to an sd-card using
+
+```
+nix build -L --show-trace .\#nixosConfigurations.sirius.config.system.build.images.sd-card
+```
+
+2. Import the `zdata`
+
+```
+zpool import zdata
+```
+
+3. Update configuration
+
+```
+clan machine update sirius
+```
