-Your script may contain place holders, that will be filled in before your connector script is executed:
-
-{endpoint}
-	When your connector is executed by a user, he will do that from the page that shows a resource. 
-	The {endpoint} placeholder contain the url of the FHIR endpoint of that resource.

+You have access to several variables that will be filled in before your connector script is executed:
+
+fhirServer
+	Wrapper of fhir.js client with a jQuery adapter. You will instantiate a new client by providing the base url and you will have
+	access to all the functionality provided by fhir.js with an embedded jQuery adapter (which is required by the plain fhir.js 		constructor). For example: 
+		.. code-block:: Javascript
+			var client = fhirServer("www.example.com");
+simplifierServer
+	Wrapper of simplifhier client which hides the fhir.js client construction. When your connector is executed by a user, he will 	do that from the page that shows a resource. The FHIR endpoint of that resource can be accessed in the following manner:
+		.. code-block:: Javascript
+			simplifierServer.ResourceEndpoint
+	You will also have access to the resource in XML and Json in case of post calls to another server
+		.. code-block:: Javascript
+			simplifierServer.ResourceXml
+			simplifierServer.ResourceJson
+	Since in essence it is a fhir.js client, simplifierServer also exposes all the methods implemented in fhir.js
+		.. code-block:: Javascript
+			simplifierServer.read(...)
+returnUrl
 	This placeholder will contain the url of the page from where your connector script is executed.
