Would be nice to get an overview of how it works (system block diagram?), how it is intended to be used, etc.  Include relevant references.  This would be a great place to document the UMD and the compiler (I am positive you have mentioned the compiler before, but I am currently failing to find a reference to it).

Accel is brand new and doesn't have that yet so I suspect we'll be well situated if we take the extra effort to spell out these things which might be just assumed elsewhere.  Hopefully, over time, such documentation helps in identifying useful areas to build up the common code of the subsystem.

OK, I've added the documentation to TODO.
For now I will add info about the compiler to v6 cover letter.
It is available at https://github.com/openvinotoolkit/vpux-plugin.
