Al-A‘la, Al-Kafirun and Al-Ikhlas are reported recitations for Witr in Sunan Abi Dawud 1423, graded sahih by al-Albani on the cited page. You do not have to memorise those particular surahs before starting. This beginner guide uses Al-Kafirun, Al-Ikhlas and Al-Falaq as practice choices, not a compulsory Witr combination.
You may see other recognised methods, including a separate final rakat or Qunut after bowing. Do not assume a different recognised practice is wrong. Explanation of differences.
The illustrated lessons teach praying alone. For Ramadan congregational Witr, learn your imam's arrangement beforehand. A Hanafi follower listens during the imam's Qur'an recitation rather than using the individual-recitation instructions here. Ask a qualified teacher about joining late or following a different Witr arrangement.
