He said I should orient me on some of the articles published in there.

This is good advice. You hopefully read a lot of papers to prepare your master's thesis. Pay attention to how they are constructed, and use that to know what a paper should look like and therefore what your paper should look like.

Papers in different fields look quite different, so general advice isn't as helpful as looking at other papers in your field.

Generally, papers are more focused on the result at hand. While they may include some background information, they aren't for demonstrating everything you know about the topic. You still want to be informative, but also concise.

Once you have a draft, ask your advisor to help you revise it. Do not take it personally if they have a lot of suggestions for changes.
