After you have understood how the process works, fill in the online application, which can be saved halfway and sent at a later stage. At the end of the form you will also see the documents that you need to include in your application.
You will also find a form which is pretty much an exam to evaluate your knowledge and understanding about the rules. After that, you basically need to pay and wait; the decision regarding your visa can take between 6 to 8 weeks.
