-Make sure you have done `npm install` to get all dependencies and used
-`ncc build index.js` before committing and opening a PR. On Ubuntu you might
+Make any changes needed to `package-lock.json` and `index.js` and open a PR.These changes will automatically be compiled into `dist/index.js` by the
+[autofix.ci bot](https://autofix.ci/).
+
+If you want to do the same work locally as the bot, use `npm install` to get
+all dependencies and then call `ncc build index.js`. On Ubuntu you might
 need to `export NODE_OPTIONS=--openssl-legacy-provider` before the `ncc build`
 step.
