 After you install Docker, you can pull the Conduit image by running the following command:
 
 ```shell
-docker pull ghcr.io/conduitio/conduit:latest
+docker pull conduit.docker.scarf.sh/conduitio/conduit
 ```
 Then, you can run Conduit by running:
 
 ```shell
-docker run -it -p 8080:8080 ghcr.io/conduitio/conduit
+docker run -it -p 8080:8080 conduit.docker.scarf.sh/conduitio/conduit
 ```
 
 The command aboves runs Conduit with no pipelines. To run Conduit with a custom pipeline file you can mount it as a volume into the container:
 ```shell
 docker run -it -p 8080:8080 \
   -v /path/to/pipeline.yaml:/app/pipelines/pipeline.yaml \
-  ghcr.io/conduitio/conduit
+  conduit.docker.scarf.sh/conduitio/conduit
 ```
 
 **Helpful Tip:** If you're using Docker, check out [Watchtower](https://containrrr.dev/watchtower/). After we push an update, Watchtower will keep your Conduit container updated by gracefully shutting down your existing container and restarting it with the same options used when initially deployed.
