Add or Update Billing Information, Change Private Repository Plan

To add payment to your account and enable private repositories, first decide whether you would like to host the private repositories under a user account or an organization. 

For a user, click the username beside the account's gravatar on the top-right of the screen to access the drop-down link for "Account Settings" (https://quay.io/user/{USER NAME}?tab=settings). 

For an organization, click the bottom "Settings" tab for the organization (https://quay.io/organization/{ORG NAME}?tab=settings).

You should see a link noting the number of private repositories available to your current plan. Click that link to change your plan, whether adding a new plan or upgrading a plan.

To change the payment option for an account, look for the "Credit Card" subheading under `Billing Information` on the account's settings page and click the link labeled "Change card".
