+Similar to any other guest langauge, there are multiple type systems in play when dealing with JS WebAssembly components.
+
+Types represented in [WebAssembly Interface Types ("WIT")][wit] must be converted down to types that are familiar for Javascript,
+and [Typescript][ts] (if dealing with `jco types` or `jco guest-types` subcommands).
+
+This document details the type representations and usage for types that are defined in WIT and built into components.

 More complicated types that are built into WIT but require more work to translate are explained below.
