Build: 
A system for assigning and grading Jupyter notebooks.
Documentation can be found on Read the Docs.
The nbgrader toolbar extension for Jupyter notebooks guides the instructor through assignment and grading tasks using the familiar Jupyter notebook interface.
The formgrader extension for the Jupyter notebook allows instructors to use the core functionality of nbgrader---generating the student version of an assignment, releasing assignments to students, collecting assignments, autograding submissions, and manually grading submissions.
Using the assignment list extension, students may conveniently view, fetch, submit, and validate their assignments.
Command line tools offer an efficient way for the instructor to generate, assign, release, collect, and grade notebooks.
