    # Introduction

    Penn Courses ([GitHub](https://github.com/pennlabs/penn-courses)) is the umbrella

    categorization for [Penn Labs](https://pennlabs.org/)

    products designed to help students navigate the course registration process. It currently

    includes three products, each with their own API documented on this page:

    Penn Course Alert, Penn Course Plan, and Penn Course Review.


    See `Penn Labs Notion > Penn Courses` for more details on each of our (currently) three apps.


    For instructions on how to maintain this documentation while writing code,

    see the comments in `backend/PennCourses/docs_settings.py` (it is easy, and will be helpful

    for maintaining Labs knowledge in spite of our high member turnover rate).


    See our [GitHub](https://github.com/pennlabs/penn-courses) repo for instructions on

    installation, running in development, and loading in course data for development. Visit

    the `/admin/doc/` route ([link](/admin/doc/)) for the backend documentation generated by Django

    (admin account required, which can be made by running

    `python manage.py createsuperuser` in terminal/CLI).


    # Unified Penn Courses

    By virtue of the fact that all Penn Courses products deal with, well, courses,

    it would make sense for all three products to share the same backend.


    We realized the necessity of a unified backend when attempting to design a new Django backend

    for Penn Course Plan. We like to live by the philosophy of keeping it

    [DRY](https://en.wikipedia.org/wiki/Don''t_repeat_yourself), and

    PCA and PCP''s data models both need to reference course and

    section information. We could have simply copied over code (a bad idea)

    or created a shared reusable Django app (a better idea) for course data,

    but each app would still need to download copies of the same data.

    Additionally, this will help us build integrations between our Courses products.


    # Authentication

    PCx user authentication is handled by platform''s Penn Labs Accounts Engine.

    See [Penn Labs Notion > Platform > The Accounts Engine](https://www.notion.so/pennlabs/The-Accounts-Engine-726ccf8875e244f4b8dbf8a8f2c97a87?pvs=4)

    for extensive documentation and links to repositories for this system. When tags or routes

    are described as requiring user authentication, they are referring to this system.


    I highly recommend the [official video course on OAuth2](https://oauth.net/2/) (by Aaron Parecki),

    then the Platform Notion docs on the "Accounts Engine" for anyone who wants to understand

    Labs authentication better. Platform is our OAuth2 "Authorization Server",

    and Django Labs Accounts is an OAuth2 client run by our Django backends (Clubs, Penn Courses, etc),

    exposing client-facing authentication routes like `penncourseplan.com/accounts/login`.

    There''s also this Wikipedia page explaining [Shibboleth](https://en.wikipedia.org/wiki/Shibboleth_(software))

    (which is used by Penn for authentication, and by the Platform authorization server).


    See the Django docs for more on Django''s features for

    [User Authentication](https://docs.djangoproject.com/en/3.0/topics/auth/),

    which are used by PCX apps, as part of Platform''s accounts system.
