-### Nginx Reverse Proxy
-
-Perplexica includes an Nginx reverse proxy that provides several key benefits:
-
-- **Single Port Access**: Access both frontend and backend through a single port (8080)
-- **Dynamic Configuration**: Works with any domain or IP without rebuilding
-- **WebSocket Support**: Automatic WebSocket URL configuration based on the current domain
-- **Security Headers**: Enhanced security with proper HTTP headers
-
-When using Docker, the reverse proxy is automatically configured. Access Perplexica at `http://localhost:8080` or `http://your-ip:8080` after starting the containers.
-
 ### Ollama Connection Errors
 
 If you're encountering an Ollama connection error, it is likely due to the backend being unable to connect to Ollama's API. To fix this issue you can:

+## Expose Perplexica to network
 
-Perplexica can be easily accessed over your home network or exposed to the internet through the Nginx reverse proxy. With this setup:
-
-1. **Local Network Access**: Access Perplexica from any device on your network using `http://server-ip:8080`
-2. **Domain Configuration**: If you have a domain name, point it to your server and access Perplexica with `http://your-domain.com:8080`
-3. **SSL Support**: Configure SSL certificates in Nginx for secure `https://` access
-
-For more network configuration details, see our [networking guide](https://github.com/ItzCrazyKns/Perplexica/blob/master/docs/installation/NETWORKING.md).

-# Exposing Perplexica to a Network
+# Expose Perplexica to a network
 
-This guide explains how to make Perplexica available over a network using the built-in Nginx reverse proxy.
+This guide will show you how to make Perplexica available over a network. Follow these steps to allow computers on the same network to interact with Perplexica. Choose the instructions that match the operating system you are using.
 
-## Accessing Perplexica Over a Network
+## Windows
 
-### Basic Access
+1. Open PowerShell as Administrator
 
-With the Nginx reverse proxy, Perplexica is automatically accessible from any device on your network:
+2. Navigate to the directory containing the `docker-compose.yaml` file
+
+3. Stop and remove the existing Perplexica containers and images:
 
-1. Start Perplexica using Docker Compose:
    ```bash
-   docker compose up -d
+   docker compose down --rmi all
    ```
 
-2. Find your server's IP address:
-   - **Windows**: `ipconfig` in Command Prompt
-   - **macOS**: `ifconfig | grep "inet "` in Terminal
-   - **Linux**: `ip addr show | grep "inet "` in Terminal
+4. Open the `docker-compose.yaml` file in a text editor like Notepad++
 
-3. Access Perplexica from any device on your network:
-   ```
-   http://YOUR_SERVER_IP:8080
-   ```
+5. Replace `127.0.0.1` with the IP address of the server Perplexica is running on in these two lines:
 
-### Domain Configuration
-
-If you have a domain name, you can point it to your server:
-
-1. Configure your domain's DNS settings to point to your server IP
-
-2. Access Perplexica via:
-   ```
-   http://your-domain.com:8080
-   ```
-
-## Advanced Configuration
-
-### Custom Port
-
-If you need to use a different port instead of the default 8080:
-
-1. Modify the `docker-compose.yaml` file:
-   ```yaml
-   nginx:
-     ports:
-       - "YOUR_CUSTOM_PORT:80"
-   ```
-
-2. Restart the containers:
    ```bash
-   docker compose down && docker compose up -d
+   args:
+     - NEXT_PUBLIC_API_URL=http://127.0.0.1:3001/api
+     - NEXT_PUBLIC_WS_URL=ws://127.0.0.1:3001
    ```
 
-### SSL/HTTPS Configuration
+6. Save and close the `docker-compose.yaml` file
 
-For secure HTTPS access:
+7. Rebuild and restart the Perplexica container:
 
-1. Modify the Nginx configuration to include SSL:
-   ```nginx
-   # In nginx.conf
-   server {
-     listen 80;
-     listen 443 ssl;
-
-     ssl_certificate /path/to/certificate.crt;
-     ssl_certificate_key /path/to/private.key;
-
-     # Rest of configuration...
-   }
-   ```
-
-2. Update the Docker volume to include your certificates:
-   ```yaml
-   nginx:
-     volumes:
-       - ./nginx.conf:/etc/nginx/nginx.conf:ro
-       - ./ssl:/path/to/ssl:ro
-   ```
-
-3. Restart the containers:
    ```bash
-   docker compose down && docker compose up -d
+   docker compose up -d --build
    ```
 
-4. Or just use another reverse proxy on top of this one...
+## macOS
 
-## Troubleshooting
+1. Open the Terminal application
 
-If you encounter issues accessing Perplexica over your network:
+2. Navigate to the directory with the `docker-compose.yaml` file:
 
-1. **Firewall Settings**: Ensure port 8080 (or your custom port) is allowed in your firewall
-
-2. **Docker Network**: Check if Docker's network settings allow external connections:
    ```bash
-   docker network inspect perplexica_perplexica-network
+   cd /path/to/docker-compose.yaml
    ```
 
-3. **Nginx Logs**: Check for any connection issues:
+3. Stop and remove existing containers and images:
+
    ```bash
-   docker logs perplexica-nginx-1
+   docker compose down --rmi all
    ```
 
-4. **Direct Access**: Verify if you can access the services directly:
-   - Frontend: http://YOUR_SERVER_IP:3000
-   - Backend: http://YOUR_SERVER_IP:3001
+4. Open `docker-compose.yaml` in a text editor like Sublime Text:
+
+   ```bash
+   nano docker-compose.yaml
+   ```
+
+5. Replace `127.0.0.1` with the server IP in these lines:
+
+   ```bash
+   args:
+     - NEXT_PUBLIC_API_URL=http://127.0.0.1:3001/api
+     - NEXT_PUBLIC_WS_URL=ws://127.0.0.1:3001
+   ```
+
+6. Save and exit the editor
+
+7. Rebuild and restart Perplexica:
+
+   ```bash
+   docker compose up -d --build
+   ```
+
+## Linux
+
+1. Open the terminal
+
+2. Navigate to the `docker-compose.yaml` directory:
+
+   ```bash
+   cd /path/to/docker-compose.yaml
+   ```
+
+3. Stop and remove containers and images:
+
+   ```bash
+   docker compose down --rmi all
+   ```
+
+4. Edit `docker-compose.yaml`:
+
+   ```bash
+   nano docker-compose.yaml
+   ```
+
+5. Replace `127.0.0.1` with the server IP:
+
+   ```bash
+   args:
+     - NEXT_PUBLIC_API_URL=http://127.0.0.1:3001/api
+     - NEXT_PUBLIC_WS_URL=ws://127.0.0.1:3001
+   ```
+
+6. Save and exit the editor
+
+7. Rebuild and restart Perplexica:
+
+   ```bash
+   docker compose up -d --build
+   ```
