+PyAssimp Readme
+===============
+
+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.
+
+![Screenshot](3d_viewer_screenshot.png)
+
+To use it, from within `/port/PyAssimp`:
+
+```console
+$ 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 ...):
+
+```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:
+
+```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:
+
+```console
+$ python setup.py install
+```
+
+PyAssimp requires a assimp dynamic library (`DLL` on windows,
+`.so` on linux, `.dynlib` 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.
