 # Configure Nydus-snapshotter
 
-Nydus-snapshotter can receive a toml file as its configurations to start providing image service through CLI parameter `--config`. A example configuration file can be found [here](../misc/snapshotter/config.toml). Besides nydus-snapshotter's configuration, `nydusd`'s configuration has to be provided to nydus-snapshotter too. Nydusd is started by nydus-snapshotter and it is configured by the provided json configuration file. A minimal configuration file can be found [here](../misc/snapshotter/nydusd-config.fusedev.json)

 ## Authentication
 
-As [contianerd#3731](https://github.com/containerd/containerd/issues/3731) discussed, containerd doesn't share credentials with third snapshotters now. Like [stargz snapshotter](https://github.com/containerd/stargz-snapshotter/blob/main/docs/overview.md#authentication), nydus-snapshotter supports 3 main ways to access registries with custom configurations. You can use configuration file to enable them.

-By setting `system.enable` to `true`,  nydus-snapshotter will start a simple HTTP serve on unix domain socket `system.address` path and exports some internal working status to users. The address defaults to `/var/run/containerd-nydus/system.sock`
