Acceptance of terms of service
Start by reading the conditions of use (it will work on your English), and check "I agree to the Terms of Service and am the rightful owner of this content.
Choose "Yes, I want to make my design available to everyone under a Creative Commons license" so that your subject is accessible to everyone.

Setting the theme
Fill in the fields (the name of the theme, the text color, description, picture in header, footer ....)
Once done, click "continue".

Your theme is now sent to the "validation".
This means that people will make sure your subject is in accordance with the Rules (no images inciting racial hatred, pornographic, ...) and validate if it is. Dont worry, they will accept it even if it is not a masterpiece ;).

Once your theme has been accepted, you will see a list of your creations.
