note that checkout instructions can be completed in any order

I have a suggestion for how to improve the checkout instructions:

I think it should be made explicit that the three checkout steps can be completed in any order.
Currently the steps are written out as a numbered list (1., 2., 3.), and to me at least, this implies that they should be completed in that specified order.

Start with the checkout instructions at checkout.html#getinvolved and review how the three steps are presented as a numbered list. Update the wording so it is explicit that the steps can be completed in any order, then verify that the rendered instructions communicate this clearly.
