The album references both the singer's personal struggles, and some of the wider issue faced by black women today and throughout history. It therefore isn't too much of a stretch to assume that the collections title is a celebration of metaphorical lemonade making: an ode to overcoming hardship, turning things around, and triumphing over adversity.
Another good way of finding more information on her Lemonade album is finding information on her songs/singles on her album. Hope I helped!
