Hello. I noticed you added material to the article Black eye but didn't cite a reliable source. You can have a look at the tutorial on citing sources, it's very easy or even automatic to add citations if you're citing a journal or a webpage, you just need the DOI or the URL. Thank you :) – Þjarkur (talk) 14:02, 30 April 2019 (UTC)
