I see that the documentation pages are IRIS CSP classes. So I guess it could work if installed in IRIS. I guess also there is a set of static files (FILECOPY could help).

IMHO, the reasonable approach to have a separate repo ensdemo-doc and a separate module the, which will be a dependent module to irishealth-ensdemo

So people could contribute to documentation independently and update it independently too.

Also available as ZPM module now: 

USER>zpm "install irishealth-ensdemo"
[irishealth-ensdemo]    Reload START (/usr/irissys/mgr/.modules/USER/irishealth-ensdemo/1.0.0/)
[irishealth-ensdemo]    Reload SUCCESS
[irishealth-ensdemo]    Module object refreshed.
