-To copy to a provider other than AWS S3 (e.g. Wasabi, Digital Ocean Spaces, etc.), you can use the command for [Copying data to Amazon S3](#copying-data-to-amazon-s3) with an added `--endpoint-url=$ENDPOINT` argument.
+To copy to a provider other than AWS S3 (e.g. Storj, Wasabi, Digital Ocean Spaces, etc.), you can use the command for [Copying data to Amazon S3](#copying-data-to-amazon-s3) with an added `--endpoint-url=$ENDPOINT` argument.
 
 Add this argument to the command **as-is** (`$ENDPOINT` is an environment variable corresponding to `matrix_synapse_ext_synapse_s3_storage_provider_config_endpoint_url`, so you don't need to touch it). Make sure to add the argument **before** the final quote (`'`) of the command.
