+# For example, if you define these variables in .gitmodules :
+# - branch-dev
+# - branch-master
+# If you are on dev branch in main project, the script will update submodule functions of branch-dev you've defined
+# In main project, if you are in another branch than master or dev, it will take by default dev branch
+# If you don't define any branches for you submodule, the script will update from master
