 To maintain consistency with the RedisArray class, one can create and connect to a cluster either by passing it one or more 'seed' nodes, or by defining these in redis.ini as a 'named' cluster.
 
 #### Declaring a cluster with an array of seeds

+```php
 // Create a cluster setting three nodes as seeds
 $obj_cluster = new RedisCluster(NULL, Array('host:7000', 'host:7001', 'host:7003'));

 #### Loading a cluster configuration by name
 In order to load a named array, one must first define the seed nodes in redis.ini.  The following lines would define the cluster 'mycluster', and be loaded automatically by phpredis.
 
-~~~ini
+```ini
 # In redis.ini
 redis.clusters.seeds = "mycluster[]=localhost:7000&test[]=localhost:7001"
 redis.clusters.timeout = "mycluster=5"
 redis.clusters.read_timeout = "mycluster=10"
 redis.clusters.auth = "mycluster=password"

 Then, this cluster can be loaded by doing the following

 $obj_cluster = new RedisCluster('mycluster');

 ## Main command loop
 With the exception of commands that are directed to a specific node, each command executed via RedisCluster is processed through a command loop, where we make the request, handle any MOVED or ASK redirection, and repeat if necessary.  This continues until one of the following conditions is met:
 
-1.  We fail to communicate with *any* node that we are aware of, in which case a ~~~RedisClusterException~~~ is raised.

 4.  We receive a valid response, in which case the data is returned to the caller.
 
 ## Transactions
 The RedisCluster class fully supports MULTI ... EXEC transactions, including commands such as MGET and MSET which operate on multiple keys.  There are considerations that must be taken into account here however.
 
-When you call ~~~RedisCluster->multi()~~~, the cluster is put into a MULTI state, but the MULTI command is not delivered to any nodes until a key is requested on that node.  In addition, calls to EXEC will always return an array (even in the event that a transaction to a given node failed), as the commands can be going to any number of nodes depending on what is called.

 ## Pipelining
 The RedisCluster class does not support pipelining as there is no way to detect whether the keys still live where our map indicates that they do and would therefore be inherently unsafe.  It would be possible to implement this support as an option if there is demand for such a feature.

 This operation can also be done in MULTI mode transparently.
 
 ## Directed node commands
 There are a variety of commands which have to be directed at a specific node.  In the case of these commands, the caller can either pass a key (which will be hashed and used to direct our command), or an array with host:port.

 The save path for cluster based session storage takes the form of a PHP GET request, and requires that you specify at least one `seed` node.  Other options you can specify are as follows:
 
 * _timeout (double)_:  The amount of time phpredis will wait when connecting or writing to the cluster.
-* _read_timeout (double)_: The amount of time phpredis will wait for a result from the cluster.
