-### 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.

-# Accessing Perplexica over a Network
+# Expose Perplexica to a network
 
-This guide explains how to access Perplexica over your network using the nginx reverse proxy included in the Docker setup.
+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.
 
-## Basic Network Access
+## Windows
 
-Perplexica is automatically accessible from any device on your network:
+1. Open PowerShell as Administrator
+
+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:
 
-## Custom Port Configuration
-
-If you need to use a different port instead of the default 8080:
-
-1. Modify the `docker-compose.yaml` file:
-   ```yaml
-   perplexica:
-     ports:
-       - "YOUR_CUSTOM_PORT:8080"
-   ```
-
-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
    ```
 
-## Troubleshooting
+6. Save and close the `docker-compose.yaml` file
 
-If you encounter issues accessing Perplexica over your network:
+7. Rebuild and restart the Perplexica container:
 
-1. **Firewall Settings**: Ensure port 8080 (or your custom port) is allowed in your firewall
-2. **Docker Logs**: Check for any connection issues with `docker logs perplexica`
-3. **Network Access**: Make sure your devices are on the same network and can reach the server
+   ```bash
+   docker compose up -d --build
+   ```
+
+## macOS
+
+1. Open the Terminal application
+
+2. Navigate to the directory with the `docker-compose.yaml` file:
+
+   ```bash
+   cd /path/to/docker-compose.yaml
+   ```
+
+3. Stop and remove existing containers and images:
+
+   ```bash
+   docker compose down --rmi all
+   ```
+
+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:
