+# Monitorcito
+
+A tiny monitor that gives you the status of a handful of systemd services.
+
+## Configuration
+
+This project uses environment variables to change configuration.
+
+* `MONITORCITO_SERVICES`: A comma separated list of services. Required.
+* `MONITORCITO_PORT`: A comma separated list of services. Defaults to 1991.
+
+
+Set `NODE_DEBUG=monitorcito` if you want to log any output. Otherwise it will
+be silent.
+
+## How to run
+
+Set the appropriate environment variables and run `bin/monitorcito`.
+
+## The Frontend
+
+Monitorcito includes a public directory, this is a frontend that queries
+the service and refreshes every 5 seconds. The service assumes the API
+is running in `/api`.
+
+Here's an example of how to set it up with nginx.
+
+```
+upstream monitorcito {
+	server localhost:1991;
+	keepalive 64;
+}
+
+server {
+	listen 80;
+
+	root /home/deploy/src/monitorcito/public;
+	index index.html;
+
+	server_name monitor.unlimited.pizza;
+
+	location /api {
+		proxy_redirect off;
+
+		proxy_pass http://monitorcito;
+	}
+}
+```
