 A demo web site using the `trustfall_wasm` package with webpack.
 It initializes the WASM module, sets up a query adapter, runs a query,
 and prints the results to `console.log()`.
+
+See the schema and query adapter used in this demo in the included `index.js`
+[file](https://github.com/obi1kenobi/trustfall/tree/main/trustfall_wasm/www/index.js)
+
+## Building and running `trustfall_wasm_www`
+
+Prerequisites:
+- a recent Rust environment: [installation instructions](https://www.rust-lang.org/tools/install)
+- the `wasm-pack` tool: [installation instructions](https://rustwasm.github.io/wasm-pack/installer/)
+- Node v16+ or newer: [installation instructions](https://nodejs.org/en/download/)
+
+First, build `trustfall_wasm` by following the steps in the `trustfall_wasm`
+[README.md](https://github.com/obi1kenobi/trustfall/tree/main/trustfall_wasm/README.md).
+When this process is complete, you should have a `trustfall_wasm/pkg/` directory in the repo
+containing the `trustfall_wasm` WASM module and supporting files.
+
+Then, run `npm install` to install the dependencies for building and running the web server.
+Finally, run `npm start` to start the webpack dev server and open a browser tab with
+the `trustfall_wasm_www` demo website.
