-## Build the Autohealer as a jar
+# Auto-healer using Zookeeper
+In cloud computing, auto-healing is a feature used to monitor a cluster and detect faulty application instances.
 
-## Run the autohealer, which in turn would launch and maintain 10 workers
+If a faulty instance is detected, the node is shut down and a new node is created with a healthy application instance.
+
+In this practical assignment we will implement a very basic auto healer which will monitor a group of worker instances.
+
+
+
+You are given a worker application
+
+The worker instances are running a very complex computation that tends to crash in a particular edge case that the author did not account for.
+
+Our mission is to maintain at least N worker nodes at any given moment.
+
+If a worker crashes, we need to start a new worker.
