 ## Introduction
 
-This GPL software calculates phonon-phonon interactions via the third order force constants. It allows to obtain lattice thermal conductivity, phonon lifetime/linewidth, imaginary part of self energy at the lowest order, joint density of states (JDOS) and weighted-JDOS. For details see Phys. Rev. B 91, 094306 (2015) and [website][a].
