The actions in my first replay still apply.

Just what do you not understand?

I consider the links very clear what to do

Links to articles on the Apple support page, like the ones lllaass provided above, are available in many languages.

If you do not understand the English articles, scroll to the bottom of the page and click on the flag. This will open a new page and allow you to select the flag of your region. Then the article will usually display in the appropriate language for that region.
