 Zigbee2MQTT uses TypeScript (partially for now). Therefore after making changes to files in the `lib/` directory you need to recompile Zigbee2MQTT. This can be done by executing `pnpm run build`. For faster development instead of running `pnpm run build` you can run `pnpm run build-watch` in another terminal session, this will recompile as you change files.
 
 Before running any of the commands, you'll first need to run `pnpm install --include=dev`.
-Before submitting changes run `pnpm run test:coverage`, `pnpm run pretty:check` and `pnpm run eslint`
+Before submitting changes run `pnpm run check:w` then `pnpm run test:coverage`.
