【How-to】When you organize a report indirectly in which order should you present your ideas

It’s not necessary to number the section headings in your report, but if you do so using a decimal system, the Introduction should be numbered 1.0, the next section should be 2.0, and so forth, with subsection headings numbered as 2.1, 2.2, etc. The References and Appendices should not have section numbers.
