Some text is duplicated (and seems to contain a typo). The text
We know will want the item we are replacing to be formatted exactly the same way as it would be without Turbo. In this case, we want a cart with the white background as it appears in the side.
appears twice: once in the beginning of the 2nd paragraph and then again in the middle of the 6th paragraph.
It should probably read ‘We now will want the item…’ (but I’m not a native English speaker).
