+Usage:
+    install-nixos.sh <HOST_NAME> <DEVICE>
+
+      Arguments
+        HOST_NAME         The networking.hostName of the installation. Something like 'velhinho-nixos'.
+        DEVICE            The LUKS device where to install to. Use lsblk or similar tools to get it's name.
+
+Examples:
+    Download install-nixos.sh and run it with 'velhinho-nixos' as hostName and '/dev/sda' as disk device:
+        curl https://euandre.org/dotfiles/install-nixos.sh > install-nixos.sh
+        chmod +x install-nixos.sh
+        ./install-nixos.sh velhinho-nixos /dev/sda
