- Refactor of StreamsContext:

Added `featuredCategories` section,
Added personalised variations of HomePage contents;
- Removal of redundant/unused files from backend;
- Update to README: Updated to current method for deploying;
- Known bug: StreamsContext is being called before AuthContext, leading to unpersonalised streams & categories each time, even when logged in;

 - React with TypeScript for type safety
 - Tailwind CSS for styling
 - Video.js for stream playback
 - Stripe integration for payment processing
 
 ### Backend
+
 - Python with Flask web framework
 - SQLite database for data persistence
 - Flask-Session for user session management
 - Nginx RTMP module for stream handling

+## Running the Current Implementation of the Project
 
-# Running the Current Implementation of the Project
 The current implementation can be run, in development mode, using the following method:
-1. With the Docker VSCode extension installed, right click within the editor with the `docker-compose.yaml` file active.
-Select `Compose Up`
-![image](https://github.com/user-attachments/assets/d68dd3b1-f3de-4780-b957-055cb536446b)
-Now the backend is up and running on `http://127.0.0.1:8080`.
-2. Next, having Node.js & Vite installed, `cd` into `web_server/frontend` and execute the command `npm run dev`. This should startup the frontend section of the application. However, this is only a temporary method as a Docker solution is in development for this frontend part of the project.
-3. Navigate to the localhost link given in the terminal upon executing the last command (`http://localhost:5173/`).
+
+- Pre-requisites:
+  - Docker
+  - Docker Compose
+  - Node.js & npm
+
+1. Replace `.env.example` with `.env` and fill in the required environment variables
+2. Launch Docker containers using either:
+   - `docker-compose up --build` in terminal
+   - Right click within the editor within `docker-compose.yml` and select `Compose Up`
+   This will start the frontend, backend, and database services
+3. Access the frontend at `localhost:8080` in your browser
