Since there's more info here then in the extension, this content should be moved to a new section rather then removed

Is there that much more information here than in the extension? Most of the extension setting descriptions provide about the same amount of information; there might be slightly more info in the docs, but I'd prefer to just change the setting descriptions, since the descriptions are all ~1 sentence anyways.
