reading databases using a customized virtual file-system

I have sqlite databases stored in something similar to a customized virtual file-system.
I want to extend sqlite.c to add support for this vfs. I did start browsing in the code, and I have some idea where to start, but any guides and tips will be very helpful and much appreciated.

I do not need any write functions though, I only wish to read databases without altering them.
