All directions are exhaustive, and in most cases will provide you with far too much detail. These instructions have been written with the assumption that the user has never done the task before, is not terribly familiar with the applications, and has just logged into the computer (no open applications other than this browser). In other words, these are written so that someone completely unfamiliar with these procedures should be able to successfully muddle through the instructions.
So if you're comfortable with the platform being utilized, use these as a basic guide. If you're delving into something completely new to you, you should be able to use the directions in conjunction with the images to get through the task.
With that said, oversights happen. If you find a confusing step or it appears that steps are missing, please let me know!
