In the third rak'ah:
1. Recite al-Fatihah and the additional Surah.
2. Raise the hands for the Qunut Takbir.
3. Say Takbir.
4. Return the hands to the standing position according to the stated Hanafi method.
5. Recite Qunut while standing.
6. Then go into Ruku.
This Qunut is before Ruku and is part of Witr throughout the year, not only in Ramadan.
The footnote separately records Qunut for a major calamity as another issue; that exception should not be confused with the ordinary Witr rule.
