+# ISO
+
+Making and writing an installable iso for `hosts/bootstrap.nix` is as simple as:
+```sh
+bud build bootstrap bootstrapIso
+sudo -E $(which bud) burn
+```
+
+This works for any host.
+
+## ISO image nix store & cache
+
+The iso image holds the store to the live environment and _also_ acts as a binary cache
+to the installer. To considerably speed up things, the image already includes all flake
+`inputs` as well as the `devshell` closures.
+
+While you _could_ provision any machine with a single stick, a custom-made iso for
+the host you want to install DevOS to, maximises those local cache hits.
+
+For hosts that don't differ too much, a single usb stick might be ok, whereas when
+there are bigger differences, a custom-made usb stick will be considerably faster.
