I used "google translate" to make this guide for you in English in order to help as many people as possible, but not being very good in English I was certainly not able to correct the majority of the mistakes.

If you see any mistakes, or poorly written sentences, don't hesitate to comment, I will change them.

Thanks for reading, and good luck with your achievement. <3
