Can we create page/assets on publish instance ?
If publish instance(4503) have all the published content from auther instance(4502) then why there is option of create site asset on publish instance?

I have created this readMe file on publish instance and able to do so ?
Also if we are able to create the content on publish then how to differentiate the content which is published from auther and which is created onn publish ?
Is there any way?
