[typo] Install help

[Jay Smith]

Hi all,

Complete newbie here. Just started with Ruby, Rails and now Typo. Now
that you've all run away I'll ask the last 3 of you:

I have managed to start the WEBrick server and have browsed to
http://localhost:3000

However I then get an error. The title of the page says: "Action
Controller: Exception Caught" and the rest of the page says: "Routing
Error
Illegal controller path for route default: articles"

Any ideas what I've done wrong? :)

Cheers
Jay
