 As of today (April 2024), ChromiumOS is the only officially supported guest
 payload. We will be adding more OSes in the future.
 
-#### Download from build server
+#### Download ChromiumOS from build server
 
-  - Step 1) Go to the link https://ci.chromium.org/ui/p/chromeos/builders/chromiumos/ferrochrome-public-main/
-    - Note: I 'searched' the ferrochrome target with builder search.
-  - Step 2) Click a build number
-  - Step 3) Expand steps and find `48. upload artifacts`.
-  - Step 4) Click `gs upload dir`. You'll see Cloud storage with comprehensive artifacts (e.g. [Here](https://pantheon.corp.google.com/storage/browser/chromiumos-image-archive/ferrochrome-public/R126-15883.0.0) is the initial build of ferrochrome)
-  - Step 5) Download `image.zip`, which contains working vmlinuz.
-    - Note: DO NOT DOWNLOAD `vmlinuz.tar.xz` from the CI.
-  - Step 6) Uncompress `image.zip`, and boot with `chromiumos_test_image.bin` and `boot_images/vmlinuz`.
-    - Note: DO NOT USE `vmlinuz.bin`.
+Download
+https://storage.googleapis.com/chromiumos-image-archive/ferrochrome-public/R128-15926.0.0/chromiumos_test_image.tar.xz.
+The above will download ferrochrome test image with version `R128-15926.0.0`.
 
-IMPORTANT: DO NOT USE `vmlinuz.bin` for passing to crosvm. It doesn't pick-up the correct `init` process (picks `/init` instead of `/sbin/init`, and `cfg80211` keeps crashing (i.e. no network)
+To download latest version, use following code.
 
+```sh
+URL=https://storage.googleapis.com/chromiumos-image-archive/ferrochrome-public
+LATEST_VERSION=$(curl -s ${URL}/LATEST-main)
+curl -O ${URL}/${LATEST_VERSION}/chromiumos_test_image.tar.xz
+```
+
+To navigate build server artifacts,
+[install gsutil](https://cloud.google.com/storage/docs/gsutil_install).
+`gs://chromiumos-image-archive/ferrochrome-public` is the top level directory for ferrochrome build.

+
+A Rust wrapper library for the VM Payload API is available (as an rlib) for VM
+payloads written in Rust.
+
+This wrapper is not guaranteed to be stable; we may change it in future
+versions. But payload code built using it will depend only on the C VM Payload
+API and the NDK APIs that are available to the payload, so should run unchanged
+on future versions.
+
+See [wrapper/lib.rs](wrapper/lib.rs) and `libvm_payload_rs` in
