Documentation is wrong

"Finally, run node server.js and visit http://localhost:3000. You should see the page working with the button." should simply say "". That's it. Don't say anything. What else happens when somebody visits a page? The page works. Whether its a 404, a 500 or otherwise, the page is still working, so there is no need to say it because it could be misunderstood by some people.

So rather than debugging and wondering if it was because I installed express@5 wondering why "if 'the page [is] working', why isn't it working", I could have just gone on to the next step but made the mistake of reading that meaningless sentence. You may say "But what if somebody is brand new?" Don't worry. It's just as meaningless to them as to everyone else.
