Edit an existing article
If you're editing an existing article, a sandbox can be a good place to copy and paste a few sentences or a paragraph to develop. Don't copy and paste the entire article into your sandbox, however.
Instead, copy the paragraph or sentences you want to work with back into the article, and then save the change.
If you're working with a new article that you've created, and doesn't exist on Wikipedia already, you can "move" your sandbox page into mainspace. In the next slides, we'll show you how.
