If I were to write a summary myself, I would first make sure that I have a clear understanding of what the article is about. If you don't understand your article, you'll have no idea what to say. To start your summary, youneed to write a thesis statement. This is generally the first sentence or the last sentence of your introductory paragraph. Once you have your introductory paragraph, you can follow the outline of the article, paragraph by paragraph, to summarize the important points made by the author of that paragraph.
