+
+[**📚 Read this template tutorial! 📚**][template-docs]
+
+This template is designed for compiling Rust libraries into WebAssembly and
+publishing the resulting package to NPM.
+
+Be sure to check out [other `wasm-pack` tutorials online][tutorials] for other
+templates and usages of `wasm-pack`.

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

+## 🔋 Batteries Included
+
+* [`wasm-bindgen`](https://github.com/rustwasm/wasm-bindgen) for communicating
+  between WebAssembly and JavaScript.
+* [`console_error_panic_hook`](https://github.com/rustwasm/console_error_panic_hook)
+  for logging panic messages to the developer console.
+* [`wee_alloc`](https://github.com/rustwasm/wee_alloc), an allocator optimized
+  for small code size.
