What key element is typically included in the conclusion of a technical document?

The conclusion of a technical document primarily serves to reinforce the information presented throughout the text. Including a summary of the main points discussed helps to encapsulate the key findings or arguments made, ensuring that the reader leaves with a clear understanding of the content. This reiteration also aids in reinforcing the document's purpose and the significance of the main ideas.

While other elements like further reading suggestions can be beneficial in certain contexts, they do not serve the primary function of the conclusion, which focuses on summarizing rather than introducing new concepts or unrelated opinions. Thus, a well-crafted conclusion that summarizes the main points solidifies the document's message and enhances the reader's comprehension.
