+## Making changes to the JavaScript
+The JavaScript does not require any build step; you just edit the files directly. However, there is config for eslint and prettier (a linter and formatter respectively); their use is recommended but not required. To use them, install `node`, run `npm i` from the root directory of this repository to install dependencies, then run `npm run lint` and `npm run format` to run eslint and prettier respectively.
