+===============================
+ Welcome to importlib_metadata
+===============================
+
+``importlib_metadata`` is a library which provides an API for accessing an
+installed package's `metadata`_, such as its entry points or its top-level
+name.  This functionality intends to replace most uses of ``pkg_resources``
+`entry point API`_ and `metadata API`_.  Along with ``importlib.resources`` in
+`Python 3.7 and newer`_ (backported as `importlib_resources`_ for older
+versions of Python), this can eliminate the need to use the older and less
+efficient ``pkg_resources`` package.
+
+``importlib_metadata`` is a backport of Python 3.8's standard library
+`importlib.metadata`_ module for Python 2.7, and 3.4 through 3.7.  Users of
+Python 3.8 and beyond are encouraged to use the standard library module, and
+in fact for these versions, ``importlib_metadata`` just shadows that module.
+Developers looking for detailed API descriptions should refer to the Python
+3.8 standard library documentation.
+
+The documentation here includes a general :ref:`usage <using>` guide.

+
+==========================
+ Using importlib_metadata
+==========================
+
+``importlib_metadata`` is a library that provides for access to installed
+package metadata.  Built in part on Python's import system, this library
+intends to replace similar functionality in ``pkg_resources`` `entry point
+API`_ and `metadata API`_.  Along with ``importlib.resources`` in `Python 3.7
+and newer`_ (backported as `importlib_resources`_ for older versions of
+Python), this can eliminate the need to use the older and less efficient
+``pkg_resources`` package.
+
+By "installed package" we generally mean a third party package installed into
+Python's ``site-packages`` directory via tools such as ``pip``.  Specifically,
+it means a package with either a discoverable ``dist-info`` or ``egg-info``
+directory, and metadata defined by `PEP 566`_ or its older specifications.
+By default, package metadata can live on the file system or in wheels on
+``sys.path``.  Through an extension mechanism, the metadata can live almost
+anywhere.
+
+
+Overview
+========
+
+Let's say you wanted to get the version string for a package you've installed
+using ``pip``.  We start by creating a virtual environment and installing
+something into it::
+
+    $ python3 -m venv example
+    $ source example/bin/activate
+    (example) $ pip install importlib_metadata
+    (example) $ pip install wheel
+
+You can get the version string for ``wheel`` by running the following::
+
+    (example) $ python
+    >>> from importlib_metadata import version
+    >>> version('wheel')
+    '0.31.1'
+
+You can also get the set of entry points for the ``wheel`` package.  Since the
+``entry_points.txt`` file is an ``.ini``-style, the ``entry_points()``
+function returns a `ConfigParser instance`_.  To get the list of command line
+entry points, extract the ``console_scripts`` section::
+
+    >>> cp = entry_points('wheel')
+    >>> cp.options('console_scripts')
+    ['wheel']
+
+You can also get the callable that the entry point is mapped to::
+
+    >>> cp.get('console_scripts', 'wheel')
+    'wheel.tool:main'
+
+Even more conveniently, you can resolve this entry point to the actual
+callable::
+
+    >>> from importlib_metadata import resolve
+    >>> ep = cp.get('console_scripts', 'wheel')
+    >>> resolve(ep)
+    <function main at 0x111b91bf8>
+
+
+Distributions
+=============
+
+While the above API is the most common and convenient usage, you can get all
+of that information from the ``Distribution`` class.  A ``Distribution`` is an
+abstract object that represents the metadata for a Python package.  You can
+get the ``Distribution`` instance::
+
+    >>> from importlib_metadata import distribution
+    >>> dist = distribution('wheel')
+
+Thus, an alternative way to get the version number is through the
+``Distribution`` instance::
+
+    >>> dist.version
+    '0.31.1'
+
+There are all kinds of additional metadata available on the ``Distribution``
+instance::
+
+    >>> d.metadata['Requires-Python']
+    '>=2.7, !=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*'
+    >>> d.metadata['License']
+    'MIT'
+
+The full set of available metadata is not described here.  See PEP 566 for
+additional details.
+
+
+Extending the search algorithm
+==============================
+
+Because package metadata is not available through ``sys.path`` searches, or
+package loaders directly, the metadata for a package is found through import
+system `finders`_.  To find a distribution package's metadata,
+``importlib_metadata`` queries the list of `meta path finders`_ on
+`sys.meta_path`_.
+
+By default ``importlib_metadata`` installs a finder for packages found on the
+file system.  This finder doesn't actually find any *packages*, but it cany
+find the package's metadata.
+
+The abstract class :py:class:`importlib.abc.MetaPathFinder` defines the
+interface expected of finders by Python's import system.
+``importlib_metadata`` extends this protocol by looking for an optional
+``find_distribution()`` ``@classmethod`` on the finders from
+``sys.meta_path``.  If the finder has this method, it takes a single argument
+which is the name of the distribution package to find.  The method returns
+``None`` if it cannot find the distribution package, otherwise it returns an
+instance of the ``Distribution`` abstract class.
+
+What this means in practice is that to support finding distribution package
+metadata in locations other than the file system, you should derive from
+``Distribution`` and implement the ``load_metadata()`` method.  This takes a
+single argument which is the name of the package whose metadata is being
+found.  This instance of the ``Distribution`` base abstract class is what your
+finder's ``find_distribution()`` method should return.
