-# Minerva Lite
+# Minerva Lite: Registration
 
-A lightweight course registration system for demonstration and testing purposes. Runs as a Flask app in a Docker container.
+Minerva Lite is a simplified web-based simulation of course registration. It is designed for demonstration, testing, and educational purposes.
 
-## Features
-- Simple course registration and schedule management
-- Minimal dependencies
-- Ready for Hugging Face Spaces deployment
+## Key Features
 
-## Usage
-This app is designed to be run as a Docker container or on Hugging Face Spaces.
+- **Term Selection:**
+  - Choose from multiple academic terms (Fall 2025, Winter 2026, Summer 2026, Fall 2026).
 
-## License
-MIT
+- **Course Search:**
+  - Search for courses by subject, number, title, or campus.
+  - View available courses for the selected term, including seat availability and schedule details.
+
+- **Add/Drop Courses:**
+  - Register for courses by entering a CRN (Course Reference Number).
+  - Drop registered courses.
+  - Registration is simulated for a single demo student.
+
+- **Student Schedule:**
+  - View your current course registrations for the selected term.
+  - See a weekly grid view of your schedule, with time blocks for each class.
+
+- **Accounts:**
+  - View a placeholder page for tuition fee and legal status (for demonstration).
+
+- **Database Reset:**
+  - Use the `/reset` endpoint to reseed the database with demo data (useful for testing or restoring the initial state).
+
+## Demo Data
+
+- The app comes preloaded with a variety of courses across multiple terms and departments (COMP, MATH, PHYS, ECON, ENGL, etc.).
+- Each course includes details such as subject, number, title, credits, days, time, campus, and seat availability.
+
+## Intended Use
+
+- This app is for demonstration and educational purposes only.
+- No real student data is used or stored.
+
+## How to Use
+
+1. **Select a term** to begin.
+2. **Search for courses** or browse available options.
+3. **Add or drop courses** using CRNs.
+4. **View your schedule** in list or weekly grid format.
+5. **Reset the database** if you want to restore the original demo data.
