We will introduce and derive the deformation invariance of plurigenera, which was proved by Y.-T. Siu [Siu 98] in the case of varieties of general type, and then by [Siu 00] in general. For the derivation, we will mainly follow the simplified proof proposed by M. Paun [Pau07] and provide enough details.
