+## RecipeStages
+You need to add the following into a CraftTweaker script:
+```
+mods.recipestages.Recipes.setPackageStage("appeng", allStages);
+```
+
+The second argument allows you to customize which stages exactly you want to be craftable with AE2. Idk why would you like to restrict any, but you can.
