 A bunch of code that messes with low level stuff. That is:
 
-- `arch/riscv/`:
-  - `machine`: prints "hello, world" on the serial port while running in M mode
-    on QEMU. Check the [README file](./arch/riscv/machine/README.md) for more
-    info.
-  - `supervisor/hsm`: using the HSM extension from SBI to gather info from
-    harts.
-  - `user/`: user space programs that either delve into RISC-V assembly or that
-    interface the Linux Kernel on the RISC-V architecture.
+- `arch/riscv/`: a bunch of samples on RISC-V running on M, S, or U mode.
 - `fs/btrfs`: miscellanous tests on BTRFS.
 - `kernel/`: samples that explore the API exposed by the Linux kernel, both from
     kernel and user space.
