Most of the first 17 chapters of this book offered you an assortment of how-to advice on improving Wikipedia articles. Now it's time to tie all that advice together, and to fill in some of the gaps.
If you're a less experienced editor, this chapter can serve as a detailed checklist. When you're looking at an article you want to improve, you have a step-by-step process for going from the top to the bottom of that article. For experienced editors, the section headings in this chapter can serve as a reminder of everything that goes into making a good Wikipedia article.
This chapter is particularly intended for articles that are short and/or relatively unsourced. It also contains a lot of advice about minimizing disagreements with other editors—a good idea even if you're working on an article where other editors are scarce to non-existent. Consider the advice about disagreements as safety insurance, in case a cranky fellow editor comes out of the woodwork.
