-Edit config:
+## Step 6 — Generate hardware configuration
-  ~/Droidnix/README.org
+
+Create the directory `~/Droidnix/generated/hosts/$HOSTNAME/` if it does not already exist.
+
+Run the following command and write its output to `~/Droidnix/generated/hosts/$HOSTNAME/hardware-configuration.nix`:
+
+```bash
+
+sudo nixos-generate-config --show-hardware-config
+
+```
+
+## Step 7 — Update [README.org](http://README.org) with generated hardware configuration
+
+In `~/Droidnix/[README.org](http://README.org)`, locate the block that begins with exactly this line:
+
+```
+
+#+BEGIN_SRC nix :tangle generated/hosts/$HOSTNAME/hardware-configuration.nix :noweb yes :mkdirp yes :eval never
+
+```
+
+and ends with the next line containing exactly `#+END_SRC`.
+
+Replace everything between (but not including) those two boundary lines with the full contents of `~/Droidnix/generated/hosts/$HOSTNAME/hardware-configuration.nix`.
+
+## Step 8 — Build and activate the NixOS configuration
+
+Change directory to `~/Droidnix` and run:
+
+```bash
+
+sudo nixos-rebuild switch --flake .#$HOSTNAME
+
+```
+
+## Step 9 — Inform the user
+
+Print the following message:
+
+```
+
+Installation complete. Please reboot your system.
+
+After rebooting, any changes to your NixOS configuration must be made in
+
+~/Droidnix/[README.org](http://README.org). Before rebuilding, first tangle the org file using:
+
+  emacs --batch --no-init-file ~/Droidnix/[README.org](http://README.org) \
+
+    --eval "(require 'org)" \
+
+    --eval "(require 'ob-tangle)" \
+
+    --eval "(find-file \"[README.org](http://README.org)\")" \
+
+    --eval "(with-temp-message \"\" (org-babel-tangle))" \
+
+    --eval "(with-temp-message \"\" (org-html-export-to-html))"
+
+Then rebuild with:
 
-Rebuild:
   cd ~/Droidnix && sudo nixos-rebuild switch --flake .#$(hostname)
 
-EOF
+```
