+# Install From NixOS Bootable Media
+
+Documented below is my process for standing up a new NixOS node configured and
+managed by this flake.
+
+## Network Access
+
+Boot the ISO (via Ventoy USB drive) and establish network access:
+
+```bash
+# plug in ethernet or do the wpa_cli song and dance
+# scan if needed
+wpa_cli scan
+wpa_cli scan_results
+
+wpa_cli add_network 0
+wpa_cli set_network 0 ssid "MY_SSID"
+wpa_cli set_network 0 psk "MY_WIFI_PASSWORD"
+wpa_cli enable_network 0
+wpa_cli save_config
+```
+
+Partition and mount disk(s) however you like. Preferably, though, use a disko
+configuration from this flake like so:
+
+```bash
+sudo nix-shell --packages git --run "
+  nix run \
+    --extra-experimental-features nix-command \
+    --extra-experimental-features flakes \
+    github:nix-community/disko -- \
+      --flake 'git+https://git.lyte.dev/lytedev/dotfiles?ref=main&dir=/os/linux/nix#diskoConfigOfChoice' \
+      --mode disko \
+      --arg disks '[ \"/dev/your_disk\" ]'
+"
+```
+
+And finally install NixOS as specified by this flake:
+
+```bash
+nix-shell --packages git \
+  --run "
+    sudo nixos-install \
+      --flake 'git+https://git.lyte.dev/lytedev/dotfiles?ref=main&dir=/os/linux/nix#yourNixosConfig'
+  "
+```
+
+**NOTE**: This takes a while, mostly due to building Helix myself on each box. I
+really need to figure out a good local caching setup.
