Just wanted to advertise that in the dev version of [openusd.org](http://openusd.org), Dan Yu has published the first of many “user guides” tackling features or areas from a user information perspective.

This one covers [Rendering with USD](https://openusd.org/dev/user_guides/render_user_guide.html) - it is not a description of Hydra behaviors, but rather a collection of the behaviors that USD expects _any_ renderer to implement, and the scene description that goes along with them. Still time to provide feedback before it appears in the 23.11 release!

Overall, a lot of great information here, reads well and is easily digestible!

Perhaps a bit tangential (and likely lies on the Hydra side of things) but a section on ensuring custom materials and lights are registered to the SdrRegistry to allow for better translation from USD & other data sources into Hydra. This may be handy, particularly outlining how to specify when type conversions need to take place and how to specify what they are; (via the SdrPropertyMetadata-\>SdrUsdDefinitionType) commonly bool → int. I imagine this could also be its own section on shader plug-ins.

This is great Sir!  
A starting point for all delegates to agree on.
