-# Rust for Linux
+# Some Modules for Rust for Linux
 
-The goal of this project is to add support for the Rust language to the Linux kernel. This repository contains the work that will be eventually submitted for review to the LKML.
+This repository contains the [Rust-for-Linux/linux](https://github.com/Rust-for-Linux/linux) kernel with some additions.
 
-Feel free to [contribute](https://github.com/Rust-for-Linux/linux/contribute)! To start, take a look at [`Documentation/rust`](https://github.com/Rust-for-Linux/linux/tree/rust/Documentation/rust).
+- `fs/bs2ramfs`
+- various additions to the kernel crate
 
-General discussions, announcements, questions, etc. take place on the mailing list at [email protected] ([subscribe](mailto:[email protected]?body=subscribe%20rust-for-linux), [instructions](http://vger.kernel.org/majordomo-info.html), [archive](https://lore.kernel.org/rust-for-linux/)). For chat, help, quick questions, informal discussion, etc. you may want to join our Zulip at https://rust-for-linux.zulipchat.com ([request an invitation](https://lore.kernel.org/rust-for-linux/CANiq72kW07hWjuc+dyvYH9NxyXoHsQLCtgvtR+8LT-VaoN1J_w@mail.gmail.com/T/)).
+For the actual work on the kernel, please refer to [Rust-for-Linux/linux](https://github.com/Rust-for-Linux/linux) and the instructions there.
 
-All contributors to this effort are understood to have agreed to the Linux kernel development process as explained in the different files under [`Documentation/process`](https://www.kernel.org/doc/html/latest/process/index.html).
