+Welcome to apipkg !
+-------------------
+
+With apipkg you can control the exported namespace of a Python package and
+greatly reduce the number of imports for your users.
+It is a `small pure Python module`_ that works on CPython 2.7 and 3.4+,
+Jython and PyPy. It cooperates well with Python's ``help()`` system,
+custom importers (PEP302) and common command-line completion tools.
+
+Usage is very simple: you can require 'apipkg' as a dependency or you
+can copy paste the ~200 lines of code into your project.
+
+
+Tutorial example
+-------------------
+
+Here is a simple ``mypkg`` package that specifies one namespace
+and exports two objects imported from different modules::
+
+
+    # mypkg/__init__.py
+    import apipkg
+    apipkg.initpkg(__name__, {
+        'path': {
+            'Class1': "_mypkg.somemodule:Class1",
+            'clsattr': "_mypkg.othermodule:Class2.attr",
+        }
+    }
+
+The package is initialized with a dictionary as namespace.
+
+You need to create a ``_mypkg`` package with a ``somemodule.py``
+and ``othermodule.py`` containing the respective classes.
+The ``_mypkg`` is not special - it's a completely
+regular Python package.
+
+Namespace dictionaries contain ``name: value`` mappings
+where the value may be another namespace dictionary or
+a string specifying an import location.  On accessing
+an namespace attribute an import will be performed::
+
+    >>> import mypkg
+    >>> mypkg.path
+    <ApiModule 'mypkg.path'>
+    >>> mypkg.path.Class1   # '_mypkg.somemodule' gets imported now
+    <class _mypkg.somemodule.Class1 at 0xb7d428fc>
+    >>> mypkg.path.clsattr  # '_mypkg.othermodule' gets imported now
+    4 # the value of _mypkg.othermodule.Class2.attr
+
+The ``mypkg.path`` namespace and its two entries are
+loaded when they are accessed.   This means:
+
+* lazy loading - only what is actually needed is ever loaded
+
+* only the root "mypkg" ever needs to be imported to get
+  access to the complete functionality
+
+* the underlying modules are also accessible, for example::
+
+    from mypkg.sub import Class1
+
+
+Including apipkg in your package
+--------------------------------------
+
+If you don't want to add an ``apipkg`` dependency to your package you
+can copy the `apipkg.py`_ file somewhere to your own package,
+for example ``_mypkg/apipkg.py`` in the above example.  You
+then import the ``initpkg`` function from that new place and
+are good to go.

+.. _`apipkg.py`: https://github.com/pytest-dev/apipkg/blob/master/src/apipkg/__init__.py

+  (using an IRC client, via webchat_, or via Matrix_).
