+The function `redisClusterContextInit` is used to create a so-called `redisClusterContext`. 
+The function `redisClusterSetOptionAddNodes` is used to add the redis cluster address. 
+The function `redisClusterConnect2` is used to connect to the redis cluser. 
+The context is where Hiredis-vip Cluster holds state for connections. The `redisClusterContext`
 struct has an integer `err` field that is non-zero when the connection is in
 an error state. The field `errstr` will contain a string with a description of
 the error.
 After trying to connect to Redis using `redisClusterContext` you should
 check the `err` field to see if establishing the connection was successful:
 ```c
-redisClusterContext *cc = redisClusterConnect("127.0.0.1:6379", HIRCLUSTER_FLAG_NULL);
+redisClusterContext *cc = redisClusterContextInit();
+redisClusterSetOptionAddNodes(cc, "127.0.0.1:6379,127.0.0.1:6380");
+redisClusterConnect2(cc);
 if (cc != NULL && cc->err) {
     printf("Error: %s\n", cc->errstr);
     // handle error
