Tutorial - Getting start - suggestion

[weierophinney]

I've found "generate-factory-for-class" very usefull, but executing it on Windows was a small problem at first.
If I could suggest a small change in this tutorial, I recomend adding a comment saying that correct syntax of this command would be:
.\vendor\bin\generate-factory-for-class "App\Action\TemplateTestAction" > src/App/src/Action/TemplateTestActionFactory.php

The biggest problem was that classname shouldn't be App\\Action\\TemplateTestAction but App\Action\TemplateTestAction. Well, at least in my environment.
