I didn't know it did, the commenter didn't mention it, and Imgur gave me an overloaded error message. (When it doesn't do that, it usually tells me it's not available in my region or that the image has been deleted anyway.)

Anyway, assuming it's for WebUSB flashing, I agree with other commenters it should just explain that's not available and still give the instructions - bonus points for hiding the unusable WebUSB option.
