Since the LaTeX wiki is a wiki, it's always in need of improvement, and you can help. When you are writing an article, and you know you should include more detail, use the template {{Improve|<reason>}} to indicate to readers and, more importantly, to future editors what improvement is needed.

Do you want to help? Look for articles in the category Improvement needed, and find the places in those articles where the words "Improvement needed" appear, and go to work!
