 This app is built with <a href="https://webpack.js.org/">Webpack</a>.
 
-When done editing `main.js`, the packed file can be built by simply running `webpack` on the command line.
-It will be writing to `dist/bundle.js`.  To run webpack in a mode so that it regularly checks for

-In a move that departs from Best Practices, I have made the decision to include the packed file in Git.
-My reason for this is that the software will be ready to run as soon as it is checked out (or a ZIP is downloaded),
-and that is a key design feature of this app--I want it to be as easy to get up and running as possible.

+A local webserver can be set up by running `npm install http-server -g` to install it, then `http-server` to listen on http://localhost:8080/

+In summary:

+- `webpack --watch`
+- `http-server`
+- `./go-sync-to-s3.sh` - Do this if you're me, to upload to S3.  If you're not me, you'll need to do something else, or possibly nothing at all.
