   # Update licenses for all selected OS
   # The matrix strategy trick is inspired from https://github.com/orgs/community/discussions/26253
+  # Basically, GitHub does not allow to have conditional statements when building matrices. One way
+  # to do it is to add new boolean fields and exclude the os name by combining them together. Then, 
+  # include the actual os using the 'include' section, which is always processed after 'exclude'
+  # based on GitHub's documentation :
+  # https://docs.github.com/en/actions/using-jobs/using-a-matrix-for-your-jobs#excluding-matrix-configurations
