 Initial conditions
 ==================
 
-Full details about the creation of the initial conditions used to run
-the FLAMINGO simulations can be found in Section 2.4 and appendix B of
+The initial conditions were generated by a modified version of 
+the `MonofonIC code
+<https://ascl.net/2008.024>`__ that implements the effects of massive neutrinos.
+The code is available `on github
+<https://github.com/wullm/monofonic>`__.
+
+All simulations in a given volume use the same phases in the initial conditions,
+allowing objects to be matched between models.
+
+Full details about the creation of the initial conditions,
+including the phases used to generate them,
+can be found in Section 2.4 and appendix B of
 `Schaye et al (2023)
 <https://ui.adsabs.harvard.edu/abs/2023MNRAS.526.4978S/abstract>`__.
