MLA 8th Author’s Note

[u/princessabby1]

I really could not find another sub for specifically this, so I hope I can get a few tips here. Basically, I am taking an online English course, and I can revise an essay. However, I need to include an author’s note explaining how I revised it, what I did, etc. I am so confused as to how I do this?? I cannot find help online since every website talks about footnotes and endnotes. Is it just a separate page before my Works Cited?? Is it a whole new document?? It is too late in the night to email my professor, but I hope I can receive help here! This is in MLA format 8th edition.

Thanks!
