-# CS3219-AY22-23-Project-Skeleton
+# PeerPrep
 
-This is a template repository for CS3219 project.
+## Overview
+PeerPrep is an application designed for programmers to find like-minded individuals to practice technical questions with. It mimics a typical technical interview format where you can perform both the role of an interviewer and interviewee, receive feedbacks and voice out your thoughts in realtime using voice or video.
 
-## User Service
-1. Rename `.env.sample` file to `.env`.
-2. Create a Cloud DB URL using Mongo Atlas.
-3. Enter the DB URL created as `DB_CLOUD_URI` in `.env` file.
-4. Install npm packages using `npm i`.
-5. Run User Service using `npm run dev`.
