Regarding the payments, international members are currently offered payments via PayPal. So if Paypal is supported in your country and if you have a Paypal account, your payments can be done via Paypal once you reach the minimum payout.
Before you start with the contributions, my suggestion would be to go through the Help section of this site and learn how this site works or operates.
If you have any kind of doubts, you can feel free to ask them through the forum section.
