-
-```
-  gem install redis

 ```
-  gem 'redis', '~>3.2'

-You can use an older version of this client if you need to interface

 You can also specify connection options as a [`redis://` URL][redis-url]:

 By default, the client will try to read the `REDIS_URL` environment variable
 and use that as URL to connect to. The above statement is therefore equivalent
 to setting this environment variable and calling `Redis.new` without arguments.
 
 To connect to Redis listening on a Unix socket, try:
 
 ```ruby
-redis = Redis.new(:path => "/tmp/redis.sock")
+redis = Redis.new(path: "/tmp/redis.sock")

 To connect to a password protected Redis instance, use:
 
 ```ruby
-redis = Redis.new(:password => "mysecret")
+redis = Redis.new(password: "mysecret")
 ```
 
 The Redis class exports methods that are named identical to the commands
 they execute. The arguments these methods accept are often identical to
 the arguments specified on the [Redis website][redis-commands]. For
 instance, the `SET` and `GET` commands can be called like this:
