Man, my Google-fu is weak. Almost all my project pages are written in Markdown, and I can't seem to find out how to put a widget onto any project page.
I have the following code from Patreon, but it doesn't show as a button widget. How do I accomplish this? For that matter, how do I do the same thing with PayPal?
