You get a working application that you can then customize thereand there while keeping something that works. This is important in agiledevelopment practices, you can right from the start of the project show thingsto customer and so take the right decision early in the process.The next steps will be to discover hooks, security, data sources, digging deeperinto view writing and interface customisation... Yet a lot of fun stuff todiscover! You will find more `tutorials and howtos`_ in the blog published on theCubicWeb.org website..._`tutorials and howtos`: http://www.cubicweb.org/view?rql=Any+X+ORDERBY+D+DESC+WHERE+X+is+BlogEntry%2C+T+tags+X%2C+T+name+IN+%28%22tutorial%22%2C+%22howto%22%29%2C+X+creation_date+D
