Compute
\[\sum_{n = 1}^\infty \frac{F_{n + 1}}{F_n F_{n + 2}},\]where $F_n$ denotes the $n$th Fibonacci number, so $F_0 = 0$ and $F_1 = 1.$
Since $F_{n + 1} = F_{n + 2} - F_n,$
\[\frac{F_{n + 1}}{F_n F_{n + 2}} = \frac{F_{n + 2} - F_n}{F_n F_{n + 2}} = \frac{1}{F_n} - \frac{1}{F_{n + 2}}.\]Then
\begin{align*}
\sum_{n = 1}^\infty \frac{1}{F_n F_{n + 2}} &= \left( \frac{1}{F_1} - \frac{1}{F_3} \right) + \left( \frac{1}{F_2} - \frac{1}{F_4} \right) + \left( \frac{1}{F_3} - \frac{1}{F_5} \right) + \dotsb \\
&= \frac{1}{F_1} + \frac{1}{F_2} \\
&= \boxed{2}.
\end{align*}
