+#pmtk3-python
+This is an experimental directory containing translations of a few 
+pmtk3 demos from Matlab to python. Over time, we hope to port
+more and more functionality.
+
+##Guide
+If you are new to using python for scientific computing, I strongly recommend 
+you to spend some time on 
+[scipy-lecture-notes](scipy-lectures.github.io).
+This document will give you a quick introduction to central tools and 
+techniques on the scientific Python ecosystem.
+
+##Requirements
+To run demos, you should have installed either python2 or python3 as you like. 
+You also need to install the following packages
+- numpy
+- scipy
+- matplotlib
+- sklearn
+- networkx
+Here are some instructions on how to install:
+- How to install Python https://wiki.python.org/moin/BeginnersGuide/Download
+- How to install numpy, scipy, matplotlib http://www.scipy.org/install.html
+- How to install sklearn http://scikit-learn.org/stable/install.html
+- How to install networkx http://networkx.github.io/documentation/latest/install.html
+
+You may also need to install some other packages. Just follow the instructions above.
+
+##How to run demos
+All you need to do is setting the PYTHONPATH
+- On linux, just put this in your ~/.bashrc
+  `export PYTHONPATH=/path/to/pmtk3/python` (without quotes)
+- On windows, you need to open
+  My Computer > Properties > Advanced System Settings > Environment Variables >
+  ![img1](http://i.stack.imgur.com/ZGp36.png)
+  Then under system variables  create a new Variable called PYTHONPATH.
+  Fill the variable value with `/path/to/pmtk3/python` (without quotes)
+
+In the future, maybe we can build a package to make things easier.
