 To include multiple metadata components, either set multiple --metadata <name> flags or a single --metadata flag with multiple names separated by spaces. Enclose names that contain spaces in one set of double quotes. The same syntax applies to --include-packages and --source-dir.
 
-To build a manifest from the metadata in an org use the --from-org flag optionally combining it with the --metadata flag to only include certain metadata types, or the --exclude-metadata flag to exclude certain metadata types. When building a manifest from an org, the command makes many API calls concurrently to discover the metadata that exists in the org. To limit the number of concurrent requests use the `SF_LIST_METADATA_BATCH_SIZE` environment variable and set it to a size that works best for your org and environment. If you are experiencing timeouts and/or inconsistent manifest contents then setting this environment variable should improve accuracy. However, the command will take longer to run since it sends fewer requests at a time.
