+# Animation Encoder
+## Overview
 anim_encoder creates small JavaScript+HTML animations from a series on PNG images.
+This is a modification of that original post, that adds some actual documentation
+cleans up the code base a bit and attempts to make it slightly more reliable. So that
+if anyone actually wants to use this is a project they can get up and running really
+quickly.
+
+
+Original details are at http://www.sublimetext.com/~jps/animated_gifs_the_hard_way.html
+
+## Getting Started (Compiling the Example)
+```
+sudo apt-get install pngcrush python-opencv python-numpy python-scipy
+python anim_encoder.py example
+firefox example.html
+```
+
+
+## Capturing your own images
+Images will be saved to capture, you simply need to run capture.py and then go about your task.
+Note you can just delete frames you don't want as you initially set up, should save you some
+time. Then to run the program just go
+
+```
+python capture.py
+```
 
-Details are at http://www.sublimetext.com/~jps/animated_gifs_the_hard_way.html
+If you need to change any settings it should be pretty simple just jump over to config.py
+and edit the configuration options.
