 ## **Using the model**
 
+Currently, the GCN3 GPU model in gem5 is only supported on the develop branch.
+Thus, you should use the develop branch when running the GCN3 model.
+We expect this support to be integrated into the gem5-v21.0 release.
+
 The [gem5 repository](https://gem5.goooglesource.com/public/gem5) comes with a dockerfile located in `util/dockerfiles/gcn-gpu/`. This dockerfile contains the drivers and libraries needed to run the GPU model
 
 The [gem5-resources repository](https://gem5.googlesource.com/public/gem5-resources/) also comes with a sample application (square) that can be used to verify that the model runs correctly.
