+
+An ASGI channel layer that uses Redis as its backing store, and supports
+both a single-server and sharded configurations, as well as group support.
+
+
+Usage
+-----
+
+You'll need to instantiate the channel layer with at least ``hosts``,
+and other options if you need them.
+
+Example:
+
+.. code-block:: python
+
+    channel_layer = RedisChannelLayer(
+        host="redis",
+        db=4,
+        channel_capacity={
+            "http.request": 200,
+            "http.response*": 10,
+        }
+    )
+
+``hosts``
+~~~~~~~~~
+
+The server(s) to connect to, as either URIs or ``(host, port)`` tuples. Defaults to ``['localhost', 6379]``. Pass multiple hosts to enable sharding, but note that changing the host list will lose some sharded data.
+
+``prefix``
+~~~~~~~~~~
+
+Prefix to add to all Redis keys. Defaults to ``asgi:``. If you're running
+two or more entirely separate channel layers through the same Redis instance,
+make sure they have different prefixes. All servers talking to the same layer
+should have the same prefix, though.
+
+``expiry``
+~~~~~~~~~~
+
+Message expiry in seconds. Defaults to ``60``. You generally shouldn't need
+to change this, but you may want to turn it down if you have peaky traffic you
+wish to drop, or up if you have peaky traffic you want to backlog until you
+get to it.
+
+``group_expiry``
+~~~~~~~~~~~~~~~~
+
+Group expiry in seconds. Defaults to ``86400``. Interface servers will drop
+connections after this amount of time; it's recommended you reduce it for a
+healthier system that encourages disconnections.
+
+``capacity``
+~~~~~~~~~~~~
+
+Default channel capacity. Defaults to ``100``. Once a channel is at capacity,
+it will refuse more messages. How this affects different parts of the system
+varies; a HTTP server will refuse connections, for example, while Django
+sending a response will just wait until there's space.
+
+``channel_capacity``
+~~~~~~~~~~~~~~~~~~~~
+
+Per-channel capacity configuration. This lets you tweak the channel capacity
+based on the channel name, and supports both globbing and regular expressions.
+
+It should be a dict mapping channel name pattern to desired capacity; if the
+dict key is a string, it's intepreted as a glob, while if it's a compiled
+``re`` object, it's treated as a regular expression.
+
+This example sets ``http.request`` to 200, all ``http.response!`` channels
+to 10, and all ``websocket.send!`` channels to 20:
+
+.. code-block:: python
+
+    channel_capacity={
+        "http.request": 200,
+        "http.response!*": 10,
+        re.compile(r"^websocket.send\!.+"): 20,
+    }
+
+If you want to enforce a matching order, use an ``OrderedDict`` as the
+argument; channels will then be matched in the order the dict provides them.
+
+``symmetric_encryption_keys``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Pass this to enable the optional symmetric encryption mode of the backend. To
+use it, make sure you have the ``cryptography`` package installed, or specify
+the ``cryptography`` extra when you install ``asgi_redis``::
+
+    pip install asgi_redis[cryptography]
+
+``symmetric_encryption_keys`` should be a list of strings, with each string
+being an encryption key. The first key is always used for encryption; all are
+considered for decryption, so you can rotate keys without downtime - just add
+a new key at the start and move the old one down, then remove the old one
+after the message expiry time has passed.
+
+Data is encrypted both on the wire and at rest in Redis, though we advise
+you also route your Redis connections over TLS for higher security; the Redis
+protocol is still unencrypted, and the channel and group key names could
+potentially contain metadata patterns of use to attackers.
+
+Keys **should have at least 32 bytes of entropy** - they are passed through
+the SHA256 hash function before being used as an encryption key. Any string
+will work, but the shorter the string, the easier the encryption is to break.
+
+If you're using Django, you may also wish to set this to your site's
+``SECRET_KEY`` setting via the ``CHANNEL_LAYERS`` setting:
+
+.. code-block:: python
+
+    CHANNEL_LAYERS = {
+        "default": {
+            "BACKEND": "asgi_redis.RedisChannelLayer",
+            "ROUTING": "my_project.routing.channel_routing",
+            "CONFIG": {
+                "hosts": ["redis://:password@127.0.0.1:6379/0"],
+                "symmetric_encryption_keys": [SECRET_KEY],
+            },
+        },
+    }
+
+``connection_kwargs``
+---------------------
+
+Optional extra arguments to pass to the ``redis-py`` connection class. Options
+include ``socket_connect_timeout``, ``socket_timeout``, ``socket_keepalive``,
+and ``socket_keepalive_options``. See the
+`redis-py documentation <https://redis-py.readthedocs.io/en/latest/>`_ for more.
+
+
+Local-and-Remote Mode
+---------------------
+
+A "local and remote" mode is also supported, where the Redis channel layer
+works in conjunction with a machine-local channel layer (``asgi_ipc``) in order
+to route all normal channels over the local layer, while routing all
+single-reader and process-specific channels over the Redis layer.
+
+This allows traffic on things like ``http.request`` and ``websocket.receive``
+to stay in the local layer and not go through Redis, while still allowing Group
+send and sends to arbitrary channels terminated on other machines to work
+correctly. It will improve performance and decrease the load on your
+Redis cluster, but **it requires all normal channels are consumed on the
+same machine**.
+
+In practice, this means you MUST run workers that consume every channel your
+application has code to handle on the same machine as your HTTP or WebSocket
+terminator. If you fail to do this, requests to that machine will get routed
+into only the local queue and hang as nothing is reading them.
+
+To use it, just use the ``asgi_redis.RedisLocalChannelLayer`` class in your
+configuration instead of ``RedisChannelLayer`` and make sure you have the
+``asgi_ipc`` package installed; no other change is needed.
+
+
+Sentinel Mode
+-------------
+
+"Sentinel" mode is also supported, where the Redis channel layer will connect to
+a redis sentinel cluster to find the present Redis master before writing or reading
+data.
+
+Sentinel mode supports sharding, but does not support multiple Sentinel clusters. To
+run sharding of keys across multiple Redis clusters, use a single sentinel cluster,
+but have that sentinel cluster monitor multiple "services". Then in the configuration
+for the RedisSentinelChannelLayer, add a list of the service names. You can also
+leave the list of services blank, and the layer will pull all services that are
+configured on the sentinel master.
+
+Redis Sentinel mode does not support URL-style connection strings, just tuple-based ones.
+
+Configuration for Sentinel mode looks like this:
+
+.. code-block:: python
+
+    CHANNEL_LAYERS = {
+        "default": {
+            "BACKEND": "asgi_redis.RedisSentinelChannelLayer",
+            "CONFIG": {
+                "hosts": [("10.0.0.1", 26739), ("10.0.0.2", 26379), ("10.0.0.3", 26379)],
+                "services": ["shard1", "shard2", "shard3"],
+            },
+        },
+    }
+
+The "shard1", "shard2", etc entries correspond to the name of the service configured in  your
+redis `sentinel.conf` file. For example, if your `sentinel.conf` says ``sentinel monitor local 127.0.0.1 6379 1``
+then you would want to include "local" as a service in the `RedisSentinelChannelLayer` configuration.
+
+You may also pass a ``sentinel_refresh_interval`` value in the ``CONFIG``, which
+will enable caching of the Sentinel results for the specified number of seconds.
+This is recommended to reduce the need to query Sentinel every time; even a
+low value of 5 seconds will significantly reduce overhead.
+
+Dependencies
+------------
+
+Redis >= 2.6 is required for `asgi_redis`. It supports Python 2.7, 3.4,
+3.5 and 3.6.
