Quran and the five pillars

I am a reverted Muslim and I am a little bit confused, so please help me.  We Muslims believe that there are 5 pillars of Islam, the Oneness of God, salah, fasting, hajj, and zakat. Where does the Holy Quran stand in these 5 pillars of Islam?

بسم الله الرحمن الرحيم

الجواب حامدا ومصليا ومسلما

The Holy Quran is the divine source from which the integral beliefs and practices of Islam are derived. It is the origin of these five pillars and it is incumbent upon every Muslim to affirm his faith in all of its commandments.

والله اعلم

Allah Knows best.
