It's best to be working on a computer with a minimum of two monitors attached, or one large monitor that is big enough to view a minimum of two screens at one time. Alternatively have two computes side by side.
Put this Website up on one monitor. Put your newly downloaded application (spreadsheet) in the other monitor.
Skim or read all the information on this web page first then go back and start opening the applications. Without skimming everything first you may be stuck thinking about things that are explained easily a bit later on. There is no ideal order for written presentation. What's best for each is individualized and it's impossible to put it in the right order for everyone.

It takes more screens than many are use to.
It takes a greater ability to read than most prefer these days.
It takes a smart person to realize they should skim an entire page or document before they start deep diving into that which is of most interest.
We have dozens of other software templates to share with you. To keep our time and costs minimized, we focus on written education and documentation because it can be edited and tweaked far easier as areas needing improvement are pointed out. Written material also provides for much faster reference material when you need to look back at something. We may add videos at a later date. If so, they will likely be "dated" within weeks or months as we upgrade and change information and documentation, but so goes the game.
