 # How it works
 
-> Describe the general architecture of your app here
+> See how the Medium.com clone (called Conduit) is built using Django REST Framework and Angular.
 
 # Getting started
 
 ## Prerequisites
+Ensure you have Python 3 and Node.js installed on your system. The current project dependency versions are:
 - Python 3.10
 - Node.js 18.5.0
 
 ## Installation
+### 1. Frontend: Choose 1 of 2 ways below:
+- Install frontend dependencies and start frontend locally:
+```shell
+npm --prefix=frontend install
+npm --prefix=frontend start
+```
+This command will install and start the Angular development server. You can access the Angular application through your web browser at `http://localhost:4200`.
+
+- Install and build frontend as static files (Choose this if you don't want to make any changes to Frontend project):
+```shell
+npm --prefix=frontend install
+npm --prefix=frontend run build
+```
+
+### 2. Backend:
+- Set up a virtual environment
 ```shell
 # Install environment and dependencies
 python3 -m venv .venv
-source .venv/bin/activate # or `.venv/Scripts/activate` on Windows
+source .venv/bin/activate
+
+# or use this command on Windows
+python3 -m venv .venv
+.venv/Scripts/activate
+```
+
+- Install backend dependencies:
+```shell
 pip install -r backend/requirements.txt
+```
 
+- Apply database migrations:
+```shell
 # Apply migrations
 python backend/manage.py migrate
+```
 
-# Install and build frontend
-npm --prefix=frontend install
-npm --prefix=frontend run build
-
+- Run the Django development server:
+```shell
 # Run server
 python backend/manage.py runserver
 ```
+
+Now, your local server should be running, and you can access this Django/Angular application through your web browser at http://localhost:8000.
