+# Nova GPU Driver
+
+Nova is a driver for GSP-based Nvidia GPUs that is currently under development
+and is being written in Rust.
+
+Currently, the objective is to upstream Rust abstractions for the relevant
+subsystems a prerequisite for the actual driver. Hence, the first mainline
+version of Nova will be a stub driver which helps establishing the necessary
+infrastructure in other subsystems (notably PCI and DRM).

+- [Official Source Tree](https://gitlab.freedesktop.org/drm/nova)
+- [Announcement E-Mail](https://lore.kernel.org/dri-devel/Zfsj0_tb-0-tNrJy@cassiopeiae/)
+
+In the source tree, the driver lives in `drivers/gpu/drm/nova`.
+
+
+## Status
+
+Currently, Nova is just a stub driver intended to lift the bindings necessary
+for a real GPU driver into the (mainline) kernel.
+
+Currently, those efforts are mostly focused on getting bindings for PCI, DRM
+and the Device (driver) model upstream.
+
+It can be expected that, as the driver continues to grow, various other abstractions
+will be needed.
+
+
+## Utilized Common Rust Infrastructure
+
+Nova depends on the Rust for Linux `staging/*` [branches](Branches.md).
+
+
+## Contributing
+
+As with every real open source program, help and participation is highly welcome!
+
+As the driver is very young, however, it is currently difficult to assign tasks
+to people. Many things still have to settle until a steadily paced workflow
+produces atomic work topics a new one can work on.
+
+If you really want to jump in immediately regardless, here are a few things you
+can consider:
+
+- Most work to do right now is with more bindings for Rust. Notably, this
+  includes the device driver model, DRM and PCI. If you have expertise there,
+  have a look at the existing code in the [topic branches](Branches.md) and see
+  if there's something you can add or improve.
+- Feel free to go over Nova's code base and make suggestions or send patches,
+  for example for improved comments, grammar fixes, improving code readability
+  etc.
+
+
+Happy hacking!
