I assumed that most people would understand the instructions being given to them in the message dialogs, and therefore would not need redundant information in the description page.
Those are not steps to run the game, they are part of the game...ie.... user name input.
I have no control over the way Google Chrome handles or highlights the information in the message dialogs. So, if there is a problem with the message being displayed, then the problem is in the browser, not the game.
