Hi, @soanna. This article is educational but I think you can make it entertaining as well. No offence but writing an article is quite a difficult endeavour and you need to incorporate some aspect which can be considered as entertaining to attract readers. Be as creative as you can and avoid writing in the WebMD-style article.

Some websites like Pixabay or Pexels offer images which are non-copyrighted and safe to use. Please refer here if you're not familiar with what I was talking about.

• Cite your article's references to make it easy for us (readers) to refer to any websites you used for further reading. Also, it is a good thing for us to give some credit to the original author.
