 A Python library for the Docker Engine API. It lets you do anything the `docker` command does, but from within Python apps – run containers, manage containers, manage Swarms, etc.
 
 ## Installation

+The latest stable version [is available on PyPI](https://pypi.python.org/pypi/docker/). Either add `docker` to your `requirements.txt` file or install with pip:
 
     pip install docker
 
-> Older versions (< 6.0) required installing `docker[tls]` for SSL/TLS support.
+If you are intending to connect to a docker host via TLS, add `docker[tls]` to your requirements instead, or install with pip:
-> This is no longer necessary and is a no-op, but is supported for backwards compatibility.
+
+    pip install docker[tls]

-Handling multiplexed streams
-============================
-
-.. note::
-      The following instruction assume you're interested in getting output from
-      an ``exec`` command. These instruction are similarly applicable to the
-      output of ``attach``.
-
-First create a container that runs in the background:
-
->>> client = docker.from_env()
->>> container = client.containers.run(
-...     'bfirsh/reticulate-splines', detach=True)
-
-Prepare the command we are going to use. It prints "hello stdout"
-in `stdout`, followed by "hello stderr" in `stderr`:
-
->>> cmd = '/bin/sh -c "echo hello stdout ; echo hello stderr >&2"'
-
-We'll run this command with all four the combinations of ``stream``
-and ``demux``.
-
-With ``stream=False`` and ``demux=False``, the output is a string
-that contains both the `stdout` and the `stderr` output:
-
->>> res = container.exec_run(cmd, stream=False, demux=False)
->>> res.output
-b'hello stderr\nhello stdout\n'
-
-With ``stream=True``, and ``demux=False``, the output is a
-generator that yields strings containing the output of both
-`stdout` and `stderr`:
-
->>> res = container.exec_run(cmd, stream=True, demux=False)
->>> next(res.output)
-b'hello stdout\n'
->>> next(res.output)
-b'hello stderr\n'
->>> next(res.output)
-Traceback (most recent call last):
-  File "<stdin>", line 1, in <module>
-StopIteration
-
-With ``stream=True`` and ``demux=True``, the generator now
-separates the streams, and yield tuples
-``(stdout, stderr)``:
-
->>> res = container.exec_run(cmd, stream=True, demux=True)
->>> next(res.output)
-(b'hello stdout\n', None)
->>> next(res.output)
-(None, b'hello stderr\n')
->>> next(res.output)
-Traceback (most recent call last):
-  File "<stdin>", line 1, in <module>
-StopIteration
-
-Finally, with ``stream=False`` and ``demux=True``, the output is a tuple ``(stdout, stderr)``:
-
->>> res = container.exec_run(cmd, stream=False, demux=True)
->>> res.output
-(b'hello stdout\n', b'hello stderr\n')
