+## Install requirements
+```sh
+pip install -r requirements.txt
+```
+
+`aggdraw` has to be installed manually, pip can't do it for you.
+
+Here are directions that should work on any 64 bit platform (tested on osx
+10.11.4)
+
+This doesn't install freetype, but I don't think its required for this project
+
+```
+cd $TMPDIR
+# or hg clone https://stefanfoulis@bitbucket.org/2degrees/aggdraw-64bits
+# instead of the next 2 commands
+wget https://bitbucket.org/2degrees/aggdraw-64bits/get/a95a86958b68.zip
+unzip a95a86958b68.zip -d aggdraw-64bits
+cd aggdraw-64bits
+/usr/local/bin/python setup.py build_ext -i
+/usr/local/bin/python setup.py install
+```
+
+## How to Use
+Not exactly sure. I think I'm supposed to run `python extract_scene.py
+generate_logo.py`, but that fails with the following error.
+
+```
+Traceback (most recent call last):
+  File "extract_scene.py", line 205, in main
+    handle_scene(SceneClass(**scene_kwargs), **config)
+  File "/Users/scott/scratch/manim/scene/scene.py", line 32, in __init__
+    self.construct(*self.construct_args)
+  File "/Users/scott/scratch/manim/./generate_logo.py", line 50, in construct
+    self.interpolation_factor
+TypeError: interpolate() takes exactly 5 arguments (4 given)
