+After installing raspberrypi-build, you can find the scripts and related files for building openEuler image of Raspberry Pi in `/opt/raspi-image-build`.
+
+To build an image, run `sudo bash create-image.sh OUTDIR`, where `OUTDIR` is the directory for storing the image and other temporary files. If `OUTDIR` does not exist, it will be created automatically.
+
+After building the image, you can find the image in `OUTDIR/raspi_output/img/` as shown in the script output.

+安装 raspberrypi-build 后，树莓派镜像构建的脚本及相关文件会保存在 `/opt/raspi-image-build`。
+
+构建镜像需执行 `sudo bash create-image.sh OUTDIR`，其中 `OUTDIR` 为构建镜像的输出目录，如不存在则会自动创建。脚本运行结束后，会提示镜像的存储位置，默认保存在 `OUTDIR/raspi_output/img/` 下。
