I wanted to start again with standard Node-RED install on my Pi4

FYI Just in case relevant it has other alternate @TotallyInformation installs

So I did  
`rm -Rf .node-red`

and then ran standard installer script

All seemed OK but before running it - I went to edit settings.js and it wasn't there ☹

Install looked fine

Or you can use `node-red admin init` to interactively create your settings file.
