+External tools
+===============
+
+Here external tools related to phono3py but supported by the groups out
+of the phono3py project are listed.
+
+Each of the tools is not supported by the phono3py project because of
+the difficulties of the maintenance and the test by main developers
+of phono3py under current style of phono3py development. However
+useful tools should be known. If developers want to use here to notify
+their tools, please contact via the phonopy mailing list.
+
+Kinetic Collective Model
+-------------------------
+
+The Kinetic Collective Model (KCM), developed by the nanoTransport
+group of the Universitat Autònoma de Barcelona, is a generalization of
+the Guyer and Krumhansl solution of the phonon Boltzmann Transport
+Equation. KCM allows to compute the thermal conductivity of
+semiconductors in a fast and low memory way from first principles
+calculations.
