A little error by me there

When you put text on a path of a circle, it goes from left to right as default, but I want the bottom half of the circle to go from left to right. In the current conditions the text us upside down.

I want to put text on a circle, but from left to right instead of the default right to left, I want to use 1 circle only, instead of 2 as the example in the tutorial shows.

Thanks
