He clicks the edit tab at the top. He clicks the sentence, fixes the typo, hits the preview button, and publishes the page without entering an edit summary. I ask him if this is what he expected, and he tells me it is.
Adding a sentence
He heads to the edit page again, and quickly clicks on different edit modes. He selects the paragraph edit modes and clicks a paragraph to find out how this works. At the end of the paragraph he adds the sentence. After checking his sentence for spelling mistakes, he publishes the page. In a glimpse he notices he didn't enter an edit summary and asks me if he should've filled this.
Adding an external link
On the edit page, he scrolls a bit to find the correct section. He selects the full editor option and clicks the link. He finds the correct section and copies the syntax of a another link. He tries to find the save button and finds it after some looking.
Adding a reference
I ask him whether or not he knows how references generally works, and he tells me correctly how it works. He moves to the full editor and he tells me he thinks it's not as clear, but more powerful than the different edit options. He copies the syntax of a reference tag. He saves the page and sees that the reference isn't quite correct but we accept how it looks now.
Changing population count
On the edit page he selects the section edit mode again. He also notices what he should've done when adding the reference. He then changes the count in the infobox, and after that he changes the count in the sentence. He publishes the page.
