I'm unsure how to link to an Unearthed Arcana. The article itself simply gives a download for a pdf. There are direct links to the pdf, but all the links download the pdf. Should I link to the article or should I link to the pdf with a warning that it will download? Are there any other options I'm missing?

These are the links in question.
