 ## Introduction
 This project is a full-stack application that is built on a microservices architecture. The backend is built using NodeJS with Express, and the frontend is built using React. PeerPrep is an application that helps students prepare for technical interviews by allowing users to match up with each other to practice and simulate a real interview environment.

 ## Project Setup
-This section will tell you how to run the application locally (either through docker-compose or without docker-compose).
+For our development environment, we use `docker-compose` to quickly set up all our microservices containers with one command.
 
-## Prerequisites
+This section will tell you how to run the application locally using `docker-compose`.
+
+### Prerequisites
 1. [Docker](https://docs.docker.com/get-docker/)
 2. [docker-compose](https://docs.docker.com/compose/install/)
 
-#### Setting up environment files
+### Step 1: Set up environment files
 There were 2 env files uploaded to Canvas, the instructions are on the README uploaded to Canvas.
 
-#### Running
-For our production/development environment, we use `docker-compose up --build` to build and run all the services; this can be done from the root directory of the project (the same level as you would see the `docker-compose.yml` in. 
+### Step 2: Run docker-compose
+1. Navigate to the root directory of this repository (where the `docker-compose.yml` is)
+2. Run `docker-compose` to build and run all the services
+    ``` bash
+    docker-compose up --build
+    ```
+
+### Step 3: Access Peerprep
+1. Open up your browser and navigate to http://localhost:3000/
 
+## Deployment
+For deployment, we use Kubernetes to orchestrate our microservices. Kubernetes provides many benefits, such as load-balancing, auto-scaling and built-in service discovery.
+Our microservices images are hosted in Docker Registry and deployed onto the cloud using Google Kubernete Engine (GKE). You may refer to our [README.md](./k8s/README.md) in the k8s folder for more information.
