+# Project Title
+
+Cluster Auto-Healer using Zookeeper and Load Balncing between Workers with Herd Effect Avoidance
+
+## Description
+
+in order to keep a distribued system or app running correctly with load balancing, certain characteristics must be acheived. we present simple idea of keeping a fixed number of wrokers in the cluster by watching the cluster by running master using zookeeper so when a worker fails, we launch a new worker. wrokers join the cluster register as znode in zookeeper and master keeps an eye on them. workers here are simplem, just printing some lines on conole.
+work is balanced among workers.
+
+## Getting Started
+### SSH
+this app uses internally ssh commands between master and slaves so ssh settings must be configured before
+and can oppen connections with no errors via exchanging keys.
+ssh command has username@host_ip to specify which host to connect and what username we login under so keys must be provided to this username.
+
+### Dependencies
+
+* zookeeper-3.9.1-dependency
+* zookeeper server running in a machine (Virtual Machine or container) with identical verison of its dependency
+
+### Installing
+* change zookeeper connection info (IP + Port) as the connection to the pre-mentioned server.
+
+### Executing program 
+java -jar AutoHealer.jar <port_number> <number_of_workers_to_maintain_on_cluster> <username@host_ip>
+and Worker.jar must be with in the same directory as AutoHealer.jar
+in linux systems AutoHealer.jar and Worker.jar must be on linux at : /root/AutoHealer/.
+
+### Logging is used
+logs are written in logs/app.log
