 # This script creates a precompiled system image for faster startup of the examples.
 # It is useful only when KiteModels.jl is checked out as a git repository
 # (i.e., used in development mode, not installed as a regular package).
+# It includes most of the dependencies of the examples, but not KiteModels.jl itself.
+# This means you can still use Revise for the main package while benefiting from 
+# faster startup of the examples.
