-## About
-
-This template is designed for depending on NPM packages that contain
-Rust-generated WebAssembly and using them to create a Website.
-
-* 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
