For someone starting out, don't go crazy adding empty accounts. Start with a small set of account like the check register or "common accounts" that have a checkings, savings, and maybe a few expenses. Start transcribing from your main or most active checking account. As you enter, you'll see and "Imbalance-USD" account get created automatically in your "transfer" column. What I found useful is to do a few of these, then switch to the accounts tab and create an account for it. Expenses like "Household", and then you can create somethng below that like Utilities. You can put all your Internet and Electricity expenses under that, of if you desire, go ahead and make sub-accounts like "Expenses:Household:Utilities:Internet". Or drop the "utilities" category altogether and embrace a more flat sty "Expenses:Internet". You can later reorganize/rename these however you want.

But once you get the first month in, you have most of your categories setup. If you start on a second month and get something new, you can let it in imbalance and come back to it a bit later. I love the autocompletion and easy account filtering/search/selection in-line.

I don't know if I do enough nowadays to really need this, but if I did, it's definitely pretty easy to work with.
