When submitting a Minimal Example how do I attach the resulting .pdf output?
StackExchange does not support file attachments. You have two options:
Take a screenshot of the relevant part of the PDF and insert it in the question. This is the best option in most cases because it focuses on the problem and it is immediately visible to readers.
Use an external file hosting service such as Dropbox or http://ge.tt to upload the PDF and link to it.
