 This is the README file for the Dr_R web application built using Django. The application is designed to provide different functionalities for students (Deimos), instructors (Phobos), and general users (Astros).
 
+### Distinctiveness and Complexity
+"It’s different from the other projects and it was complex to build." Haha
+
+Jokes aside, it is a *physics* learning management system which differs a lot from other projects because of functionalities like comparing algebraic expressions and units; dynamic question creation page which acts as a GUI compiler that has to test various user input and take care of different formats like floats, multiple choice questions, latex equation, variables etc;
+a semantic search engine; etc etc
+
+### Files
+One of the submission requirements was to explain what is in every file I created but this project is relatively huge compared to previous projects, so I created a separate md file for essential documentation. Filename: documentation.md
+
+## PreRequisites
+Having Python installed on your machine and your PATH environment variable having a path to your Python's Scripts folder.

+### NOTE
+- MAC users: I have not tested those instructions on MAC, so I recommend that you skip setting up a
+virtual environment if the command does not work (skip step 3 and 4). 
+- Window users: if the command at step 3 does not work for you, just skip it. Or use "python" instead of
+ "python3."

+### Testing
+In case you want to test without having to create accounts, courses, etc, don't worry. A copy 
+of the site is running at https://mars-valpo.com. You can use the following credentials:
