 # UT Registration Plus
 
-## Built Using
+We've all been there. 20 tabs of Rate My Professor, Google Spreadsheet, and the UT Course Schedule open and you still don't know what classes to take.
+This extension, UT Registration Plus (UTRP), tries to streamline most of the unnecessary steps and headaches of registering for classes at UT Austin.
 
--   React 18
--   TypeScript
--   Vite 5
--   ESLint
--   Prettier
--   Semantic-Release
--   Custom Messaging & Storage Wrappers
+- For each class in the UT Course Schedule site, UTRP provides a "breakdown" popup, with quick and easy links to the instructor's RateMyProfessor, Course Evaluation Survey (CES) and past syllabi.
 
-## Getting Started
+- Shows the course description with highlighted information on prerequisites, restrictions, etc.
+
+- Shows an aggregate and semesterly graph of the grade distributions for each course.
+
+- Gives you the ability to add "Add Course" and view them in the extension popup, a quick list of all the courses you have saved and an easy way to copy unique numbers.
+
+- Highlights and crosses-out what courses on the UT Course Catalog would conflict with your currently saved courses, making selecting courses that fit with your schedule so much easier.
+
+- Display's a weekly schedule based on your saved courses.
+
+- Give you the ability to create multiple schedules to plan for different scenarios.
+
+- ... and much more!
+
