Content-Type isn't multipart/form-data

I have this curl syntax which uploads a file to my server just fine

curl http://localhost:8844/upload_04_curl -F ‘fileupload=@board.jpeg’

so am trying to translate that curl syntax into postman … I see the import menu where I give it my local file board.jpeg however its not clear where to give it a form data flavor as in curl syntax of

-F ‘fileupload=@board.jpeg’

so my server errors with

request Content-Type isn’t multipart/form-data

and in particular I cannot find where in Postman I qualify my form to know the key is “fileupload”

Maybe this tutorial can help you get started:
