Hi @hmouhtar,

Great that you are trying out O3. Pleas keep in mind that it is only going through its [first alpha release](https://talk.openmrs.org/t/releasing-o3-ref-app-3-0-0-alpha/37757).

There is a GP to control how demo data is generated I think, @ruhanga could you point to the right direction here?

For your own deployment however you will probably want to have your own distro depend and repackage O3, as it is done in Ozone for instance, see [here](https://github.com/ozone-his/ozone-distro#1-overview). There, you could also decide to exclude the Reference Demo Data module - that would be my preferred approach.

Yes, by all means.
