+        *****************
+
+        For creating 'safeloader' images for tp-link devices.
+
+        These can be flashed to the device using the firmware update feature
+        in the TP-link web UI or the OEM bootloader recovery: Use something
+        sharp to hold the 'reset' button while turning on the router until
+        only the orange LED remains lit. The router will assume IP address
+        192.168.0.1 and expect you to take 192.168.0.5 on one of the LAN ports.
+        On NixOS, use something like::
+
+            networking.interfaces.enp0s20f0u1c2 = {
+              ipv4.addresses = [ {
+                address = "192.168.0.5";
+                prefixLength = 24;
+              } ];
+            };
+            networking.networkmanager = {
+                unmanaged = [ "enp0s20f0u1c2" ];
+            };
+
+        This connection is rather somewhat temperamental, it may take a couple
+        of attempts, possibly re-attaching the USB dongle and running
+        ``systemctl restart network-start.service``. The web interface does not
+        give accurate feedback (the progress bar is a lie), so you may want
+        to upload the firmware using ``curl -F firmware=@result http://192.168.0.1/f2.htm``.
+        After this shows a 'success' JSON, the image still needs to be
+        transferred from memory to flash, so be patient.
+      '';
+    };
+  };
