+## Development
+
+#### post_save_hook
+* Copy the content of utils/post_save_hook.py to your jupyter_notebook_config.py before making changes to notebooks
+* This will setup a post_save_hook which will generate a html version of the notebook automatically when the notebook is saved
+* htmls are not generated for exercises
+
+#### Testing
+* Travis CI will make sure that the code cells in the notebooks can be executed
+* You test the same locally by:
+    * install tox by: `pip install tox`
+    * run tox: `tox`
+* Tests are not run for exercises (because the code in the exercise cells is usually intentionally incomplete)
