+PyAssimp: Python bindings for libassimp
+=======================================
+
+A simple Python wrapper for Assimp using ``ctypes`` to access the
+library. Requires Python >= 2.6.
+
+Python 3 support is mostly here, but not well tested.
+
+Note that pyassimp is not complete. Many ASSIMP features are missing.
+
+USAGE
+-----
+
+Complete example: 3D viewer
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+``pyassimp`` comes with a simple 3D viewer that shows how to load and
+display a 3D model using a shader-based OpenGL pipeline.
+
+.. figure:: 3d_viewer_screenshot.png
+   :alt: Screenshot
+
+   Screenshot
+
+To use it, from within ``/port/PyAssimp``:
+
+::
+
+    $ cd scripts
+    $ python ./3D-viewer <path to your model>
+
+You can use this code as starting point in your applications.
+
+Writing your own code
+~~~~~~~~~~~~~~~~~~~~~
+
+To get started with ``pyassimp``, examine the simpler ``sample.py``
+script in ``scripts/``, which illustrates the basic usage. All Assimp
+data structures are wrapped using ``ctypes``. All the data+length fields
+in Assimp's data structures (such as ``aiMesh::mNumVertices``,
+``aiMesh::mVertices``) are replaced by simple python lists, so you can
+call ``len()`` on them to get their respective size and access members
+using ``[]``.
+
+For example, to load a file named ``hello.3ds`` and print the first
+vertex of the first mesh, you would do (proper error handling
+substituted by assertions ...):
+
+.. code:: python
+
+
+    from pyassimp import load
+    with load('hello.3ds') as scene:
+
+        assert len(scene.meshes)
+        mesh = scene.meshes[0]
+
+        assert len(mesh.vertices)
+        print(mesh.vertices[0])
+
+
+Another example to list the 'top nodes' in a scene:
+
+.. code:: python
+
+
+    from pyassimp import load
+    with load('hello.3ds') as scene:
+
+        for c in scene.rootnode.children:
+            print(str(c))
+
+
+INSTALL
+-------
+
+Install ``pyassimp`` by running:
+
+::
+
+    $ python setup.py install
+
+PyAssimp requires a assimp dynamic library (``DLL`` on windows, ``.so``
+on linux, ``.dylib`` on macOS) in order to work. The default search
+directories are:
+
+-  the current directory
+-  on linux additionally: ``/usr/lib``, ``/usr/local/lib``,
+   ``/usr/lib/x86_64-linux-gnu``
+
+To build that library, refer to the Assimp master ``INSTALL``
+instructions. To look in more places, edit ``./pyassimp/helper.py``.
+There's an ``additional_dirs`` list waiting for your entries.
