-* `build_web.sh` compiles your code to wasm and puts it in the `docs/` folder (see below)
 * `start_server.sh` starts a local HTTP server so you can test before you publish

+* `build_web.sh` compiles your code to WASM and puts it in the `docs/` folder (see below) and `--open` opens the result in your default browser.
 
 The finished web app is found in the `docs/` folder (this is so that you can easily share it with [GitHub Pages](https://docs.github.com/en/free-pro-team@latest/github/working-with-github-pages/configuring-a-publishing-source-for-your-github-pages-site)). It consists of three files:
