 = USAGE:
 
+Some caveats at the moment:
+
+Minimum requirements for users databag format:
+
+Users
+-id
+--groups
+---sysadmin
+--htaccess // in order to have access to site through webui
+--icinga
+---email // this key must exist for each user with a sysadmin group value (above)
+
+Note: the htpasswd value must be generated with: `htpasswd -nb <username> <password>`
+
+Also, you will need one node with a "monitoring" role (I applying it to my icinga node,
+and this can be just a skeleton. This is just so that one of the templates generates correctly,
+and this requirement will likely be alleviated in future versions.
