Calculus derivatives

What is the second derivative of $h(x)=g(f(x))$ I was able to find the first derivative which is $h'(x)=g'(f(x))\cdot f'(x)$ I know for the second derivative we are going to need to use both the chain rule and product rule but I am unsure how

$$h(x)=g(f(x))$$ $$h'(x)=g'(f(x))\times f'(x)$$ $$h''(x)=g''(f(x))\times f'(x)\times f'(x) + g'(f(x))\times f''(x)$$ $$h''(x)=g''(f(x))\times (f'(x))^2 + g'(f(x))\times f''(x)$$
