+    # PyZMQ: Python bindings for ØMQ
+
+    This package contains Python bindings for [ZeroMQ](https://zeromq.org).
+    ØMQ is a lightweight and fast messaging implementation.
+
+    PyZMQ should work with any reasonable version of Python (≥ 3.8), as well as PyPy.
+    PyZMQ supports libzmq ≥ 3.2.2 (including 4.x).
+
+    For a summary of changes to pyzmq, see our
+    [changelog](https://pyzmq.readthedocs.io/en/latest/changelog.html).
+
+    ### ØMQ 3.x, 4.x
+
+    PyZMQ fully supports the stable (not DRAFT) 3.x and 4.x APIs of libzmq,
+    developed at [zeromq/libzmq](https://github.com/zeromq/libzmq).
+    No code to change, no flags to pass,
+    just build pyzmq against the latest and it should work.
+
+    ## Documentation
+
+    See PyZMQ's Sphinx-generated
+    documentation [on Read the Docs](https://pyzmq.readthedocs.io) for API
+    details, and some notes on Python and Cython development. If you want to
+    learn about using ØMQ in general, the excellent [ØMQ
+    Guide](http://zguide.zeromq.org/py:all) is the place to start, which has a
+    Python version of every example. We also have some information on our
+    [wiki](https://github.com/zeromq/pyzmq/wiki).
+
+    ## Downloading
+
+    Unless you specifically want to develop PyZMQ, we recommend downloading
+    the PyZMQ source code or wheels from
+    [PyPI](https://pypi.io/project/pyzmq/),
+    or install with conda.
+
+    You can also get the latest source code from our GitHub repository, but
+    building from the repository will require that you install recent Cython.
+
+    ## Building and installation
+
+    For more detail on building pyzmq, see [our docs](https://pyzmq.readthedocs.io/en/latest/howto/build.html).
+
+    We build wheels for macOS, Windows, and Linux, so you can get a binary on those platforms with:
+
+    ```
+    pip install pyzmq
+    ```
+
+    but compiling from source with `pip install pyzmq` should work in most environments.
+    Make sure you are using the latest pip, or it may not find the right wheels.
+
+    If the wheel doesn't work for some reason, or you want to force pyzmq to be compiled
+    (this is often preferable if you already have libzmq installed and configured the way you want it),
+    you can force installation from source with:
+
+    ```
+    pip install --no-binary=pyzmq pyzmq
+    ```
+
+    ## Old versions
+
+    pyzmq 16 drops support Python 2.6 and 3.2.
+    If you need to use one of those Python versions, you can pin your pyzmq version to before 16:
+
+    ```
+    pip install 'pyzmq<16'
+    ```
+
+    For libzmq 2.0.x, use 'pyzmq\<2.1'
+
+    pyzmq-2.1.11 was the last version of pyzmq to support Python 2.5,
+    and pyzmq ≥ 2.2.0 requires Python ≥ 2.6.
+    pyzmq-13.0.0 introduces PyPy support via CFFI, which only supports libzmq-3.2.2 and newer.
+
+    PyZMQ releases ≤ 2.2.0 matched libzmq versioning, but this is no longer the case,
+    starting with PyZMQ 13.0.0 (it was the thirteenth release, so why not?).
+    PyZMQ ≥ 13.0 follows semantic versioning conventions accounting only for PyZMQ itself.
