 If nodesource.com doesn't yet support your OS
 ---------------------------------------------
 
-If nodesource.com [does not yet support your Linux OS (they often support Debian pre-releases, but generally not other OS pre-releases)](https://github.com/nodesource/distributions#deb) then you can manually install an older version of Node.js and npm as follows:
+If nodesource.com [does not yet support your Linux OS (they often support Debian pre-releases, but generally not other OS pre-releases)](https://github.com/nodesource/distributions#deb) and IIAB's asked to install Node.js, it will do the equivalent of:
 
 - `sudo apt install nodejs npm`
 - `sudo echo 'nodejs_installed: True' >> /etc/iiab/iiab_state.yml`
 
-Best to do this prior to installing IIAB!
+AT YOUR OWN RISK, you can later run `cd /opt/iiab/iiab` then `sudo ./runrole --reinstall nodejs` if you really want to **wipe** your OS's own versions of Node.js and npm, and attempt the Nodesource approach instead.

 Raspberry Pi Zero W Warning
 ---------------------------
 
-Node.js applications like Asterisk/FreePBX, Node-RED and Sugarizer won't work on Raspberry Pi Zero W (ARMv6) if you installed Node.js while on RPi 3, 3 B+ (ARMv7) or RPi 4 (ARMv8).
+UPDATE: The Zero 2 W released 2021-10-28 is 64-bit (ARMv7) so may or may not have such serious problems...
 
-If necessary, run `apt remove nodejs` or `apt purge nodejs` then `rm /etc/apt/sources.list.d/nodesource.list; apt update` then ([attempt!](https://nodered.org/docs/hardware/raspberrypi#swapping-sd-cards)) to [install Node.js](https://github.com/iiab/iiab/blob/master/roles/nodejs/tasks/main.yml) _on the Raspberry Pi Zero W itself_ (a better approach than "cd /opt/iiab/iiab; ./runrole --reinstall nodejs" is to try `apt install nodejs` or try installing the tar file mentioned at [#2082](https://github.com/iiab/iiab/issues/2082#issuecomment-569344617)).
+On the original Raspberry Pi Zero W (ARMv6) however: Node.js applications like Internet Archive, JupyterHub, Node-RED, PBX (Asterisk/FreePBX) and Sugarizer won't work — if you installed Node.js while on Raspberry Pi 3, 3 B+ (ARMv7) or Raspberry Pi 4 (ARMv8).
 
-You'll (likely) also need `apt install npm`.
+If necessary, run `sudo apt purge nodejs npm` then `sudo rm /etc/apt/sources.list.d/nodesource.list` then  `sudo apt update` and then attempt to [install Node.js](https://github.com/iiab/iiab/blob/master/roles/nodejs/tasks/install.yml) _on the Raspberry Pi Zero W itself_ (`cd /opt/iiab/iiab` then `sudo ./runrole --reinstall nodejs`).
 
-Whatever versions of Node.js and npm you install, make sure `/etc/iiab/iiab_state.yml` contains the line `nodejs_installed: True` (add it if nec!)  Finally, proceed to install Asterisk/FreePBX, Node-RED and/or Sugarizer: [#1799](https://github.com/iiab/iiab/issues/1799)
+Earlier, some preferred installing the tar file version mentioned at [#2082](https://github.com/iiab/iiab/issues/2082#issuecomment-569344617) — if that is your preference, consider a more recent version like: https://nodejs.org/dist/latest-v18.x/
+
+Either way, you'll (likely) then also need to run: `sudo apt install npm`
