 3. For intermediate points, the values of `x` must be in the interval `0..1`, `y` can be anything.
 
+If you're not familiar with Bezier curves yet, you might want to check the [Bezier curve](/bezier-curve) chapter of the tutorial.

 The syntax for a Bezier curve in CSS: `cubic-bezier(x2, y2, x3, y3)`. Here we need to specify only 2nd and 3rd control points, because the 1st one is fixed to `(0,0)` and the 4th one is `(1,1)`.
 
 The timing function describes how fast the animation process goes.
