 ### Run via Docker
 
 Be aware that as this runs inside a container it mounts your current directory as a volume, and for the -d flag you need to use the path inside the container.
 
 ```bash
-docker run -it --rm -v $(pwd):/import ghcr.io/immich-app/immich-cli:latest upload --email testuser@email.com --password password --server http://192.168.1.216:2283/api -d /import
+docker run -it --rm -v $(pwd):/import ghcr.io/immich-app/immich-cli:latest upload --key HFEJ38DNSDUEG --server http://192.168.1.216:2283/api -d /import
 ```
 
 Optionally, you can create an alias:
 
 ```bash
 alias immich="docker run -it --rm -v $(pwd):/import ghcr.io/immich-app/immich-cli:latest"
-immich upload --email testuser@email.com --password password --server http://192.168.1.216:2283/api -d /import
