+Replace `REPOSITORY-URI` with the URI from `aws ecr create-repository` (above).
 
 Note: it doesn't make much sense to load a multiplatform image into your local Docker registry as your local Docker installation supports only your current host platform, but you can do so if you wish by replacing `--push` with `--load`.
