Outline of proposed changes
I was thinking of adding more to the history section. That will be my primary edit. I would like to add more information on the inventor(s) of the cement truck, the purpose behind making it, and the advancements made throughout the years. I would also like to add more pictures to the article and correct the citations that need verification, as there are quite a few.
