 The Wasm [HTTP middleware]({{< ref middleware.md >}}) allows you to rewrite a
 request URI with custom logic compiled to a Wasm binary. In other words, you
 can extend Dapr using external files that are not pre-compiled into the `daprd`
-binary. Dapr embeds [wazero][https://wazero.io] to accomplish this without CGO.

+Minimally, a user must specify a Wasm binary that contains the custom logic

+concurrently. The below configuration fields control both the binary to
+instantiate and how large an instance pool to use. A larger pool allows higher
