 A lightweight load-balancer written in Node.js which is highly available. It's made using the Reactor pattern in Node along with support for worker processes (one per core). You can however run a simple load-balancer with a single process by disabling the multiCore feature.
 
 The load-balancer is programmed for high availability i.e if the worker process gets killed, it will be restarted. This ensures that the load on the other processes doesn't increase substantially.
 
+You can also configure an smtp server with `heinrich`. Mails will be sent whenever one or more of the backend servers go down.
+
 Currently you'll have to clone the project & run the main file. I'll be writing installation & startup scripts for ubuntu & centos servers.
