After i submitted my app to the Tizen app challenge, I recieved this email :

“Please note, if you submitted prior to achieving certification in the Tizen Store, your submission will not be eligible until this process completes. If you’ve already achieved certification for Tizen 2.2, you’re all done!”

Can you please tell me what does it mean and how  can I achieve certification in the Tizen Store or certification for Tizen 2.2?
Thank you.
