 ### ClangScraper
 
-Mod categories:
+Mod categories: Creation
+
+This is a critical mod used to generate the initial set of raw C# bindings for C APIs. The use of this mod is equivalent
+to using `ClangSharpPInvokeGenerator`. The C# source code generated by this mod is typically the starting point for all
+of the transformations done by the rest of the SilkTouch mods.
 
 Usage recommendations:
 
+This mod is configured differently from the rest of the mods. The JSON mod configuration follows the same pattern as the
+rest of the mods, but the bulk of the configuration comes in the form of `.rsp` files. These `.rsp` files represent the
+command line arguments passed to `ClangSharpPInvokeGenerator`. More information about how to use this mod and how to
+configure the generator as a whole is found in the [Using the Generator](using-the-generator.md) documentation.
+
+This mod should be positioned at the start of the mod order, after `AddIncludes`.
