+# Kubemq hazelcast Target Connector
+
+Kubemq hazelcast target connector allows services using kubemq server to access hazelcast server functions such `set`, `get` and `delete`.
+
+## Prerequisites
+The following are required to run the hazelcast target connector:
+
+- kubemq cluster
+- hazelcast
+- kubemq-targets deployment
+
+## Configuration
+
+hazelcast target connector configuration properties:
+
+| Properties Key            | Required| Description                  | Example          |
+|:--------------------------|:--------|:-----------------------------|:-----------------|
+| address                   | yes     | hazelcast connection string                     | "localhost:5701" |
+| username                  | no      | hazelcast username                              | "admin" |
+| password                  | no      | hazelcast password                              | "password" |
+| connectionAttemptLimit    | no      | hazelcast connection attempts(default 1)        | 1                            |
+| connectionAttemptPeriod   | no      | hazelcast attempt period seconds(default 5)     | 5 |
+| connectionTimeout         | no      | hazelcast connection timeout seconds(default 5) | 5 |
+| ssl                       | no      | hazelcast use ssl                               | false |

+| sslcertificatekey         | no      | hazelcast certificate key                       | "" |
+| serverName                | no      | hazelcast server name                           | "myserver" |
+
+Example:
+
+```yaml
