+## Extending
+
+### Functionality
+
+To make the app more interactive, see code samples in the [Getting Started](https://v3.vuejs.org/guide/introduction.html#getting-started) docs.
+
+### Components
+
+To load components on the frontend as `.vue` files, see my [No build step](https://michaelcurrin.github.io/code-cookbook/recipes/javascript/packages/vue/no-build-step.html) guide. That also makes it easier to use scoped CSS.
+
+Though, if you have a couple of components or your entire site is Vue pages (compared with adding Vue to HTML), then consider structuring your application as a Vue Node app that uses Vue CLI for developing tooling and optimized production builds (like for compiling and minifying).

+
+### Structure
+
+This project deviates from the typical Vue CLI quickstart app. Part of the intention here is to show to add Vue to an existing site - so some content has been added directly to [index.html](/index.html) outside of the app. The CSS has been adjusted to be on `body` not `#app`.
+
+A better setup for this project would be showing how to use some components like todo app or counter. And not necessarily in `app`. These could be on more targeted IDs. Need to research this approach as it is different from setting up a single app as entry-point.
 
 ### Formatting

 But you can run Prettier ad hoc like this to format the JS file, assuming you have Node installed.
