+# Self-Hosted: Process monitoring and startup
+Usually, you want this program to run as a service, wich can restart itself in case of crashing, and on every reboot.
+This is possible vía [pm2, the nodejs process manager](http://pm2.keymetrics.io/).
+
+1. Run the program using some pm2 flags. You can name processes, I used `--name email`. The `--watch` option restarts the app when dies for any reason.
+```
+cd void-mail
+pm2 --name email start npm -- start --watch
+```
+
+2. Save your current list of running processes, so them resurrect when you reboot.
+`pm2 save`
+
+3. Make your system to run it on boot/reboot. You can run it with sudo directly.
+`pm2 startup`
+
+4. Once you did this, you can try to reboot things.
+- Reboot your system and check if void-mail gets started. (`reboot`)
+- Kill node app instance and see if gets respawned (ie `kill -9 ``pgrep node`` `)
