 ## Example usage of CLoudEvents sdk/Reqwest from WASM
 
-Install the dependencies with:
+First, ensure you have [`wasm-pack` installed](https://rustwasm.github.io/wasm-pack/installer/)
+
+Then install the dependencies:
 
     npm install
 
-Then build the example locally with:
+And finally run the example:
 
     npm run serve
 
-and then visiting http://localhost:8080 in a browser should run the example!
+You should see a form in your browser at http://localhost:8080. When
+the form is submitted, a CloudEvent will be sent to the Target URL,
+http://localhost:9000 by default, which is the default URL for the
+[actix example](../actix-web-example). Fire it up in another terminal
+to verify that the data is successfully sent and received.
+
+Open the javascript console in the browser to see any helpful error
+messages.
 
-This example is loosely based off of [this example](https://github.com/rustwasm/wasm-bindgen/blob/master/examples/fetch/src/lib.rs), an example usage of `fetch` from `wasm-bindgen`, and from [reqwest repo](https://github.com/seanmonstar/reqwest/tree/master/examples/wasm_github_fetch).
+This example is loosely based off of [this
