+# Writing a connector script
+
+There are several things that you will likely do when you write a connector script. And to make this as easy as possible, your script will have access to the following Javascript libraries:
+- JQuery 1.7
+- JQuery.Redirect 1.0.1
+- Fhir.js
+
+
+If you wish to fetch data from a server
+	.. code-block:: Javascript
+	$.get("spark.furore.com/fhir/Patient/1").succes(function()
+	{
+
+	});
+
+To redirect to a different page:
+
+Place holders
+-------------
+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.
+
+## {returnurl}
+This placeholder will contain the url of the page from where your connector script is executed.
