This article is about how to format an article. It discusses the different sections that should be included and what they should include. This section includes a sentence on what this section is about, which in this case would be formatting articles correctly.
Introduction – This section should briefly introduce the article and what it is about.
Section One: What to include in this section?
Section Two: What to include in this section?
Conclusion – This sentence will conclude the post, maybe with a call to action for readers or an invitation for them to contact you if they have any questions. The introduction, sections, and conclusion all come after one another within the body of your content.
They are not separate from each other like headers are (or indented paragraphs). It might be helpful to think of these three parts as sentences that come together without punctuation at first glance.
