Reionization represents a fundamental transition in the universe's properties, and yet, we know little about how it occurred. The most likely explanation is that Lyman continuum (LyC) radiation escaped into the intergalactic medium from early star-forming galaxies. However, most star-forming galaxies show no signs of LyC escape. Recently, the ``Green Pea" galaxies have emerged as the first known star-forming galaxy population where strong LyC escape is common. I will discuss what we are learning from the Green Peas about ways to identify LyC-leaking galaxies, the role of feedback in LyC escape, and the properties of LyC-emitters.
