WHen you are writting instructions to someone about anything, you have different options to do so, if you do a flow chart, that means that you have a specifical way and order to do the things, as well as a diagram, if you do a list, this can be in order of importance, and when doing a paragraph you give equal importance to all of the pieces, because you need them all in order to do something. In this case, it´s a paragraph because you need all of those things in the request in order to be valid.
