Thanks Ermin,

I've seen a lot of these links myself, but none provide the context I need to know where to start. Appreciate you sharing the links you have been collecting. I'm collecting a whole library as I go. The level of documentation for Odoo is appalling. You expect to pay for integration and major customisation, but the basics, there should be good documentation. Take Postbooks as an example. Their doco is extraordinary allowing the inhouse support and integrator to really get places.

I'll keep looking and experimenting and post anything I find. Python is not my native programming language which doesn't help.

I should probably also clarify that I'm happy to use the same theme for both my websites, but just need a different color scheme. I can't even do that out of the box. Potentially this is an easier task

It seems to be possible, but not easy.

These are the links concerning multi-website I have collected so far:
