     Installation
     ============
 
-    Installation is currently a manual process.

+    factory, so a one-time step is needed to prepare it before Liminix

-     This is a manual process: you need a :ref:`serial <serial>` conection and TFTP : follow the instructions at :ref:`system-outputs-ubimage`
+    The default target for this device is ``outputs.ubimage`` which
+    makes a ubifs image suitable for use with :command:`ubiupdatevol`.
+    For a first-time installation the simplest way to achieve this is
+    using the OpenWrt recovery system that you installed in the
+    previous step. In this configuration the device assigns itself the
+    IP address 192.168.1.1/24 on its LAN ports and expects the
+    connected computer to have 192.168.1.254
 
-'';
+    The `ubi0_7` device in these instructions is correct as of Dec
+    2024 (dangowrt/owrt-ubi-installer commit d79e7928). If you are
+    installing some time later, it is important to check the output
+    from :command:`ubinfo -a` and make sure you are updating the
+    "liminix" volume and not some other one which had been introduced
+    since I wrote this.
