The 仓库 contains two main files FreeCodeCamp_presentation.ipynb and Tutorial.ipynb which I used to deilver the talk and tutorial on the Friday 18th Aug 2017 meetup.
If you wonder what the ipynb extentions exists for, it is, ipython notebook.
They have been created by an open-source web application called Jupyter (http://jupyter.org/).
If you have any questions or suggestions please feel free to contact me.
