+## About
+
+[**📚 Read this template tutorial! 📚**][template-docs]
+
+This template is designed for compiling Rust libraries into WebAssembly and
+publishing the resulting package to NPM.

+cd my-project
+```
+
+### 🛠️ Build with `wasm-pack build`
+
+```
+wasm-pack build
+```
+
+### 🔬 Test in Headless Browsers with `wasm-pack test`
+
+```

+
+This template is designed for depending on NPM packages that contain

+
+* Want to create an NPM package with Rust and WebAssembly? [Check out
+  `wasm-pack-template`.](https://github.com/rustwasm/wasm-pack-template)
+* Want to make a monorepo-style Website without publishing to NPM? Check out
+  [`rust-webpack-template`](https://github.com/rustwasm/rust-webpack-template)
+  and/or
+  [`rust-parcel-template`](https://github.com/rustwasm/rust-parcel-template).
+
+## 🚴 Usage
+
+```
+npm init wasm-app
+```
+
+## 🔋 Batteries Included
+
+- `.gitignore`: ignores `node_modules`
+- `LICENSE-APACHE` and `LICENSE-MIT`: most Rust projects are licensed this way, so these are included for you
+- `README.md`: the file you are reading now!
+- `index.html`: a bare bones html document that includes the webpack bundle
+- `index.js`: example js file with a comment showing how to import and use a wasm pkg
+- `package.json` and `package-lock.json`:
+  - pulls in devDependencies for using webpack:
+      - [`webpack`](https://www.npmjs.com/package/webpack)
+      - [`webpack-cli`](https://www.npmjs.com/package/webpack-cli)
+      - [`webpack-dev-server`](https://www.npmjs.com/package/webpack-dev-server)
+  - defines a `start` script to run `webpack-dev-server`
+- `webpack.config.js`: configuration file for bundling your js with webpack
