Anisotropic flow studies play a crucial role in the characterization of the nature of the quark gluon plasma (QGP) created in collisions of heavy ions at ultra-relativistic energies. These studies rely on measuring the coefficients vn of the Fourier expansion of the azimuthal particle distribution. They have been essential in establishing that the QGP is a strongly coupled, almost perfect fluid. In this seminar, I review the latest results from measurements of elliptic (v2), triangular (v3), quadrangular (v4) and pentagonal (v5) flow of identified particles at the LHC measured with ALICE. I will discuss how these results allow us to gain insight into the transport properties of the QGP and the initial conditions of a heavy-ion collision. In addition, they reveal the role of different hadronisation mechanisms as well as the highly dissipative hadronic rescattering phase to the development of vn. .
