In the generic repository, the Set Me Up gives curl instructions for resolving and deploying artifacts. There is a space before the API key:
curl -H 'X-JFrog-Art-Api: AKCp5aTvABKQkSG4D4tjCtCFj1QRqH8fgkMiJEizARtoZTJxuzeYDYZS353v68jHMrXZ7zKe3' -T <PATH_TO_FILE> "http://mill.jfrog.info:12195/artifactory/generic-local/<TARGET_FILE_PATH>"
This works fine in a linux/OSX terminal. It fails in a Windows terminal. Space should be removed as that will work in both terminals.
