I could only make it like five minutes, but this is a great summary by the AP:

In first half hour of debate, a raspy Biden has delivered rambling answers that sometimes trail off as he defends his policies and record.

Trump has countered with falsehoods on issues including the economy, abortion and NATO members’ defense spending.

The two have also exchanged deeply personal attacks.
