When editing your pages or posts you quickly add a donation button with the ‘Add Donation’ button found at the top of the Admin Editor.
When you click on that button it will pop open a little window with some options. All the options are explained in full in the shortcode documentation. This helper button simply exists to hopefully save you some time in creating the button with some specific options.
Hit ‘Insert Stripe Donation Button’ at the bottom and it will automatically put the shortcode in the spot where you cursor is located. You can modify that shortcode directly in the editor to change, add or remove other attributes.
