-By default, the adapter uses `NebulexRedisAdapter.ClientCluster.Keyslot` for the
-keyslot. Besides, if `:jchash` is defined as dependency, the adapter will use
-consistent-hashing automatically.
-
-> **NOTE:** It is highly recommended to define the `:jchash` dependency
-  when using the adapter in `:client_side_cluster` mode.
-
-However, you can also provide your own implementation by implementing the
-`Nebulex.Adapter.Keyslot` and set it into the `:keyslot` option. For example:
-
-```elixir
-defmodule MyApp.ClusteredCache.Keyslot do
-  use Nebulex.Adapter.Keyslot
-
-  @impl true
-  def hash_slot(key, range) do
-    # your implementation goes here
-  end
-end
-```
-
-And the config:
-
-```elixir
-config :my_app, MyApp.ClusteredCache,
-  # Enable client-side cluster mode
-  mode: :client_side_cluster,
-
-  client_side_cluster: [
-    # Provided Keyslot implementation
-    keyslot: MyApp.ClusteredCache.Keyslot,
-
-    # Nodes config (each node has its own options)
-    nodes: [
-      ...
-    ]
-  ]
-```
-
-### Using `Nebulex.Adapters.Partitioned`
-
-Another simple option is to use the `Nebulex.Adapters.Partitioned` and set as
-local cache the `NebulexRedisAdapter`. The idea here is each Elixir node running
-the distributed cache (`Nebulex.Adapters.Partitioned`) will have as local
-backend or cache a Redis instance (handled by `NebulexRedisAdapter`).
-
-
-This example shows how the setup a distributed cache using
-`Nebulex.Adapters.Partitioned` and `NebulexRedisAdapter`:
-
-```elixir
-defmodule MyApp.DistributedCache do
-  use Nebulex.Cache,
-    otp_app: :my_app,
-    adapter: Nebulex.Adapters.Partitioned,
-    primary_storage_adapter: NebulexRedisAdapter
-end
-```

 ### Using a Redis Proxy
 
 The other option is to use a proxy, like [Envoy proxy][envoy] or
 [Twemproxy][twemproxy] on top of Redis. In this case, the proxy does the
-distribution work, and from the adparter's side (**NebulexRedisAdapter**),
+distribution work, and from the adparter's side (**Nebulex.Adapters.Redis**),
 it would be only configuration. Instead of connect the adapter against the
 Redis nodes, we connect it against the proxy nodes, this means, in the config,
 we setup the pool with the host and port pointing to the proxy.

-## Running Redis commands and/or pipelines
+## Using the adapter as a Redis client
 
-Since `NebulexRedisAdapter` works on top of `Redix` and provides features like
-connection pools and "Redis Cluster" support, it may be seen also as a sort of
-Redis client, but it is meant to be used mainly with the Nebulex cache API.
-However, Redis API is quite extensive and there are a lot of useful commands
-we may want to run taking advantage of the `NebulexRedisAdapter` features.
-Therefore, the adapter injects two additional/extended functions to the
-defined cache: `command!/2` and `pipeline!/2`.
