 By default, the adapter will use `Dalli::Client.new('localhost:11211', { namespace: 'hikki', compress: true })` as
 it's connection.
 You can pass in your own connection to use instead, useful for specifying a server, namespace and other options.
 
 ```ruby
+require 'memcache_adapter'
+
 # Use the default connection
 adapter = Hikki::Adapters::MemcacheAdapter.new
 
 # Use a specific connection
 cache = Dalli::Client.new('cache.example.com:11211', { namespace: 'my_cache' })
