 ## Development
 
-To run the visualization locally, first run `npm install` to install the development dependencies.
-Then run `npm run watch` to start a watcher that automatically compiles the typescript files to a bundled js,
-whenever they change. Finally, run `npm run serve` which starts an HTTP server serving all files in the `public` folder.
-To see the visualization, visit `http://localhost:8080/` on your browser.
+To run the visualization locally you just need a server to serve all the files from the `dist` directory. You can run `npm install` then `npm run serve` if you don't have one handy. To see the visualization, visit `http://localhost:8080/` on your browser.
+
+When developing, use `npm run serve-watch`. This will start a static server and also watchers to automatically compile the typescript, html and css files
+whenever they change.
+
 To produce a minified javascript file for production, run `npm run build`.
