 ### Sentinel support
 
 The client is able to perform automatic failover by using [Redis Sentinel](https://redis.io/docs/manual/sentinel/).

+### `*_v` methods
+
+In some it's more convenient to pass commands as arrays, for that `_v` versions of `call` methods are available.
+
+```ruby
+redis.call_v(["MGET"] + keys)
+redis.blocking_call_v(1, ["MGET"] + keys)
+redis.call_once_v(1, ["MGET"] + keys)
+```

 ### Blocking commands
 
 For blocking commands such as `BRPOP`, a custom timeout duration can be passed as first argument of the `#blocking_call` method:
 
 ```
 redis.blocking_call(timeout, "BRPOP", "key", 0)
 ```
 
-If `timeout` is reached, `#blocking_call` returns `nil`.
+If `timeout` is reached, `#blocking_call` raises `RedisClient::ReadTimeoutError` and doesn't retry regardless of the `reconnect_attempts` configuration.
 
 `timeout` is expressed in seconds, you can pass `false` or `0` to mean no timeout.
