+Troubleshooting
+---------------

+1. If you get `error: implicit declaration of function x; did you mean function y? [-Wimplicit-function-declaration]`, check and update the `firefly-scene` and `firefly-display` submodules in the components folder:
+
+```sh
+# check the submodules are from the correct branch
+git submodule status
+
+# update the submodules
+git submodule update --init --recursive
+
+# pull submodules changes from the remote repositories
+git pull --recurse-submodules
+```
