 ## Usage
 
-By default, *sql.js* uses [wasm](https://developer.mozilla.org/en-US/docs/WebAssembly), and thus needs to load a `.wasm` file in addition to the javascript library. You can find this file in `./node_modules/sql.js/dist/sql-wasm.wasm` after installing sql.js from npm, and add it to your static assets or load it from a CDN. Then use the [`locateFile`](https://emscripten.org/docs/api_reference/module.html#Module.locateFile) property of the configuration object passed to `initSqlJs` to indicate where the file is. If you use an asset builder such as webpack, you can automate this. See [this demo of how to integrate sql.js with webpack (and react)](https://github.com/sql-js/react-sqljs-demo).
