 #### `make uninstall`
 Removes Agones from the Kubernetes cluster
 
+#### `make update-allocation-certs`
+Updates the Agones installation with the IP of the Allocation LoadBalancer, thereby creating a valid certificate
+for the Allocation gRPC endpoints.
+
+The certificates are downloaded from the test kubernetes cluster and stored in ./build/allocation
+
 #### `make test-e2e`
 Runs end-to-end tests on the previously installed version of Agones.
 These tests validate Agones flow from start to finish.
