If your group is editing an existing article, a sandbox can be a good place to prepare your first updates by copying a small portion of the article that you want to change or extend. Do not try to overhaul an entire article from the sandbox.

First identify as a group what's missing from the current article. Keep reading your sources, too, as you prepare to write the body of the article.

When you're ready to make edits:

1. Open your group's chosen article in Edit mode. (References and other templates will break if you copy from Read mode.)
2. Select the portion you want to work on — a few paragraphs at most — and copy it.
3. Open the sandbox your group has decided to work in, and open the Edit mode. Now paste the copied article content.
4. Add an edit summary that says copied from [[article]] with the name of the original article, then save it by clicking Publish changes.
5. Re-enter Edit mode in the sandbox, make your changes, and publish them.
