 <!-- AUTO-GENERATED-CONTENT:END -->
 
-This package uses pm2 to setup a cross-package hot reloading solution.
-When you run `pnpm run start` it will start multiple processes with pm2.
-pm2 is configured using the [pm2 ecosystem file](./pm2.ecosystem.config.js) and [pm2's offical documentation](https://pm2.keymetrics.io/docs/usage/quick-start/).
-Here are a few helpful commands:
-
--   `pm2 list <name of app in pm2.ecosystem.config.js>` Shows all currently running processes managed by pm2 and the status they are in.
--   `pm2 log <name of app in pm2.ecosystem.config.js>` Shows the typical logs for a given process, what you'd expect to see if you started the app without pm2.
--   `pm2 delete <name of app in pm2.ecosystem.config.js>` Deletes a specific process managed by pm2
--   `pm2 delete all` Deletes all the processes managed by pm2
-
-`pnpm run stop` will stop all the processes managed by pm2.
-Use it when you're done testing this application so no processes are left in the background re-compiling the projects on every change.
