Q: How do I write an article?
Hello Lindsay – Welcome to the forum! Now, you have a very simple question. So, we shall provide a very simple answer. :-)
If you mean structuring the paper, you need to follow the IMRaD (Introduction > Methods > Results > analysis > Discussion) structure. You may learn more about it (including ways to go about writing your paper as per the structure) in this excellent article: Tips for writing the perfect IMRAD manuscript
If you mean the actual writing, here is an all-inclusive resource (a resource that includes many other resources within) that you may refer to: The complete guide to writing a brilliant research paper
Hope these can get you started on your writing. :-) All the best!
