Not an American so I probably should not complain. But when I opened the page out of curiosity for the first time, I found many terms that require explanations, such as what is AGI? The "What Is IRS Free File?" section below it explained most of my questions, so I think the "What Is IRS Free File?" section should exchange it place with the "Choose from IRS Free File" section. This allows the reader to have a clearer mind when preforming the filing process. Just my two cents. I wouldn't take the matter lightly though, because based on my understanding and what I've learned from the movie Everything Everywhere All At Once, IRS tax filing is a serious manner thus the tools designed to do that should be more user-friendly. I don't think getting kungfu-attacked by the IRS lady is enjoyable for any American (as well as going to jail/getting fined for misfiling).
