+# Simple example of a plugin system using libloading and stabby
+
+## Shared
+
+This contains the shared types, need to look at traits too.
+
+## Plugin
+
+This contains the code for the example plugin. I would like it if it didn't depend on stabby.
+For now I need it though, to export the function. Maybe this can be "fixed" with traits in the shared library.
+
+## Main
+
+This contains the code that calls the plugin.
