+# Vanilla OS CN Waydroid Image
+
+This image is based on the Vanilla OS Desktop Waydroid image.
+
+## Changes
+
+- Replace Debian APT sources with TUNA mirrors for mainland China users.
+- Add IBus Chinese input methods: libpinyin and Rime.
+
+## Build
+
+```bash
+vib build recipe.yml
+podman image build -t vanillaos/waydroid-cn .
+```
+
+## Container registry mirrors
+
+The image includes mainland China container registry mirror defaults:
+
+- Docker Engine uses `https://docker.nju.edu.cn` as the Docker Hub registry mirror.
+- Podman, Buildah, and Skopeo use:
+  - `docker.io` -> `docker.nju.edu.cn`
+  - `ghcr.io` -> `ghcr.nju.edu.cn`
+
+Docker Engine only supports transparent registry mirrors for Docker Hub. For GHCR with Docker, pull from the mirror domain explicitly, for example:
+
+```bash
+docker pull ghcr.nju.edu.cn/vanilla-os/desktop:main
+```
