 * This stack has for purpose to know if all promises, services, custom monitoring scripts went/are ok.
+* The second purpose of this stack is to implement a zero-knowledge feature : it means you can use its control interface to provide the user with sensible data. It can also let the user change some parameters
+* It also provides a web interface, to see which promises, services and custom scripts failed. It also provide a rss feed to easily know the actual state of your instance, and to know when it started to went bad.

+Implementation :
+----------------
 1/ In the software.cfg of your Software Release, extends the stack
 2/ In the template that will be copied for the buildout in the instance folder (instance.cfg ?), you have to add these parts:
+###Parts to add for monitoring
+  slap-parameters
   certificate-authority
-  ca-nginx
-  directory
-  deploy-monitor-script
-  deploy-rss-script
   cron
   cron-entry-monitor

+  publish-connection-parameter
 
 * If you want to add a custom monitoring script, you can write it (in whatever language you wish) and save it in YOUR_INSTANCE_FOLDER/etc/monitor.
 The only thing to know, is that if your script successfully passed, do not return or print nothing. If there is a problem, you can print the explanation on stdout or stderr
