 Nerdctl supports to convert an OCI image or docker format v2 image to Nydus image by using the `nerdctl image convert` command.
 
-Before the conversion, you should have the `nydus-image` binary installed, which is contained in the ["nydus static package"](https://github.com/dragonflyoss/image-service/releases). You can run the command like `nerdctl image convert --nydus --oci --nydus-image <the_path_of_nydus_image> <source_image> <target_image>` to convert the `<source_image>` to a Nydus image whose tag is `<target_image>`.

You can run the command like `nerdctl image convert --nydus --oci --nydus-builder-path <the_path_of_nydus_image_binary> <source_image> <target_image>` to convert the `<source_image>` to a Nydus image whose tag is `<target_image>`.
 
 By now, the converted Nydus image cannot be run directly. It shoud be unpacked to nydus snapshotter before `nerdctl run`, which is a part of the processing flow of `nerdctl image pull`. So you need to push the converted image to a registry after the conversion and use `nerdctl --snapshotter nydus image pull` to unpack it to the nydus snapshotter before running the image.
