Center the documentation body

[voronokKita]

Hello. In your documentation, the body with text is shifted to the right from the center. This creates discomfort, because you need to squint to the right all the time.
It is good when the text is in the center. Or shifted slightly to the left, since most people read from left to right, and this does not cause discomfort.
Maybe you could just swap the nav block from left to right.
