 ## Provided Libraries
 For each assignment, you will use the geometry processing library [libigl](https://github.com/libigl/libigl/), which includes implementations of many of the algorithms presented in class.
-In particular you will be using the [python bindings of igl](https://libigl.github.io/libigl-python-bindings/).
+In particular, you will be using the [python bindings of igl](https://libigl.github.io/libigl-python-bindings/).
 
 The `libigl` library includes a set of tutorials, an introduction to which can be found in the two previous links. You are advised to look over the relevant tutorials before starting the implementation for the assignments; you are also encouraged to examine the source code of all the library functions that you use in your code to see how they were
 implemented.
 
 No libraries apart from `libigl`, `numpy`, `meshplot`, and `scipy` are permitted unless permission is granted in advance.
 
-## Video Report
+## Report
 
-For every assignment, you have to provide a video report of a maximal lenght of 3 minutes. The video should contain either captions explaining what you did and the results of your assignment or a voice commentary. To prepare the video, I recommend to use either the recording option in NYU Zoom (you can create a call with only you, share the window with your browser, and then press record) or OBS (https://obsproject.com/). The video should be in a format playable using the VLC player (https://www.videolan.org/vlc/).
+For every assignment, you should provide a report in the form of a runnable Jupiter notebook including results for all steps described in the assignment. Please also add illustrations and text as needed to explain what you did. In addition to the notebook, you should also attach an html version of the notebook, exported using ``nbconvert``.
