1. **State the problem:** Simplify the expression $$\frac{y+1}{y^{2}-4} - \frac{5}{y+2}$$.
2. **Recall the formula and rules:**
- Factor the denominator if possible.
- Find a common denominator to combine the fractions.
- Simplify the resulting expression.
3. **Factor the denominator:**
$$y^{2}-4 = (y-2)(y+2)$$
4. **Rewrite the expression with factored denominator:**
$$\frac{y+1}{(y-2)(y+2)} - \frac{5}{y+2}$$
5. **Find the common denominator:**
The common denominator is $(y-2)(y+2)$.
6. **Rewrite the second fraction with the common denominator:**
$$\frac{5}{y+2} = \frac{5(y-2)}{(y+2)(y-2)}$$
7. **Combine the fractions:**
$$\frac{y+1}{(y-2)(y+2)} - \frac{5(y-2)}{(y-2)(y+2)} = \frac{y+1 - 5(y-2)}{(y-2)(y+2)}$$
8. **Simplify the numerator:**
$$y+1 - 5(y-2) = y + 1 - 5y + 10 = -4y + 11$$
9. **Final simplified expression:**
$$\frac{-4y + 11}{(y-2)(y+2)}$$
This is the simplified form of the given expression.
