+Server Monitoring based on Dropbox
+==================================
+
+Overview
+--------
+
+Monitor the health of your servers and receive alerts when something goes wrong.
+This web application is built with the Opa technology and runs on top of a Dropbox-based database.
+
+Demo
+----
+
+Main website and live demo at <a href="http://server-monitor.herokuapp.com/">http://server-monitor.herokuapp.com/</a>
+
+Dropbox Storage
+---------------
+- All your configured jobs and logs are saved on your personal Dropbox account. Nothing is stored on the application server.
+- If one of your sever goes down, a Dropbox popup will appear on your desktop.
+
+The following code is a Dropbox database in Opa. Change the `@dropbox` annotation with `@mongo` and the app will run on top of MongoDB instead. It's that simple.
+
+	database monitor @dropbox {
+	    stringmap(log) /logs
+	    stringmap(job) /jobs
+	    /logs[_]/status = { ok } // Define the default "status" value
+	}
+
+	function add(name, url, freq){
+		/monitor/jobs[name] <- (~{ url, freq })
+	}
+
+__Note:__ This application is a proof of concept, aim to learn the <a href="http://opalang.org">Opa Framework</a> and to present a Dropbox-based database use case. The <a href="http://server-monitor.herokuapp.com/demo">demo</a> will stop monitoring your servers as soon as you close the  page: fork the project and make you own production-ready version!
+
+Compile
+-------
+
+<a href="http://opa.io">Download and install Opa</a>, then compile the single file:
+
+    opa main.opa
+
+
+Run
+---
+
+<a href="https://www.dropbox.com/developers/apps">Create an app on Dropbox website</a> and use the app keys to start the application:
