+
+<p><strong>Objective: Introduce the concept of tasks and how simple trigger 
works</strong></p>
+
+<p><strong>Prerequisites:</strong><br>
+You will need access to build the SimpleStockQuoteService as mentioned in the 
above and start the
+sample axis2 server before staring synapse.</p>
+
+<p>When ever synapse gets started and initialized, this task will run 
periodically in 5 second
+intervals. You could limit the number of times that you want to run this task 
by adding a count
+attribute with an integer as the value, if the count is not present as in this 
sample this task will
+run forever.</p>
+
+<p>One can write his own task class implmenting the 
org.apache.synapse.startup.Task interface and
+implementing the execute method to do the task. For this particualr sample we 
have used the
+MessageInjector which just injects a message specified in to the synapse 
enviorenemnt.</p>
