To install kafka , I downloaded the kafka tar folder. To start the server I tried this command :
bin/zookeeper-server-start.sh config/zookeeper.properties
The following error occured on entering the above command:
INFO Reading configuration from: config/zookeeper.properties (org.apache.zookeeper.server.quorum.QuorumPeerConfig)

Is it that I need to setup zookeeper separately? How could I resolve this?

If one the ZooKeeper nodes fails, the following occurs: Other ZooKeeper nodes detect the failure to respond. A new ZooKeeper leader is elected if the failed node is the current leader. If multiple nodes fail and ZooKeeper loses its quorum, it will drop into read-only mode and reject requests for changes.
Replacing ZooKeeper with internally managed metadata will improve scalability and management, according to Kafka's developers. Change is coming for users of Apache Kafka, the leading distributed event-streaming platform.
In Kafka architecture, Zookeeper serves as a centralized controller for managing all the metadata information about Kafka producers, brokers, and consumers. However, you can install and run Kafka without Zookeeper.
For Windows:
