 2. When detected, it focuses the terminal and allows user input
 3. User input is captured in the terminal component's inputBuffer
 4. When the user presses Enter, the input is:
-    - Sent to the backend via WebSocket.
-    - Displayed in the terminal.
-    - Buffer is cleared for next input.

 - Limited CPU and memory resources
 - Limited file system access
 - No persistent storage

+# Monaco Backend - Tunnel Only Setup
+
+This setup runs **only the Cloudflare tunnel** in Docker, while the backend runs **outside Docker on port 9090**.
+
+## Prerequisites
+
+1. Backend must be running on port 9090 on your local machine
+2. Required files in this directory:
+   - `cert.pem` - Cloudflare tunnel certificate
+   - `credentials.json` - Cloudflare tunnel credentials
+   - `config.tunnel-only.json` - Tunnel configuration (points to port 9090)
+
+## Setup
+
+### 1. Start your backend on port 9090
+
+Run your Go backend locally:
+```bash
+# Option 1: Run directly
+PORT=9090 go run main.go
+
+# Option 2: Build and run
+go build -o main
+PORT=9090 ./main
+```
+
+### 2. Start the tunnel
+
+In this directory, run:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+Or run in detached mode:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build -d
+```
+
+### 3. Check logs
+
+```bash
+docker-compose -f docker-compose.tunnel-only.yml logs -f
+```
+
+## How It Works
+
+1. The tunnel container runs only `cloudflared`
+2. It connects to Cloudflare's edge network
+3. Traffic from `api.ishikabhoyar.tech` is routed through the tunnel
+4. The tunnel forwards requests to `host.docker.internal:9090` (your local backend)
+5. Your backend on port 9090 handles the requests and sends responses back
+
+## Configuration
+
+The tunnel is configured in `config.tunnel-only.json`:
+```json
+{
+  "tunnel": "5d2682ef-0b5b-47e5-b0fa-ad48968ce016",
+  "credentials-file": "/etc/cloudflared/credentials.json",
+  "ingress": [
+    {
+      "hostname": "api.ishikabhoyar.tech",
+      "service": "http://host.docker.internal:9090"
+    },
+    {
+      "service": "http_status:404"
+    }
+  ],
+  "protocol": "http2",
+  "loglevel": "info"
+}
+```
+
+## Troubleshooting
+
+### Tunnel can't reach backend
+- Make sure your backend is running on port 9090
+- Test locally: `curl http://localhost:9090`
+- Check firewall settings
+
+### Tunnel connection issues
+- Verify `credentials.json` and `cert.pem` are valid
+- Check tunnel status in Cloudflare dashboard
+- Review logs: `docker-compose -f docker-compose.tunnel-only.yml logs -f`

+## Notes
+
+- The tunnel only forwards traffic; it doesn't run the backend
+- Backend must be started before or after the tunnel (order doesn't matter)
+- If backend restarts, tunnel will automatically reconnect

+# Tunnel Connection Options - Troubleshooting Guide
+
+## The Problem
+When the tunnel runs in Docker and tries to reach your backend on the host, there are different ways to address the host machine. The method that works depends on your Docker setup.
+
+## Solution 1: Direct Bridge IP (config.tunnel-only.json) ✅ WORKING
+
+**Files:** 
+- `Dockerfile.tunnel-only`
+- `docker-compose.tunnel-only.yml`
+- `config.tunnel-only.json` (updated to use `172.18.0.1:9090`)
+
+**How it works:**
+- Uses the Docker bridge network IP directly
+- You verified this works: `curl 172.18.0.1:9090` ✅
+
+**Usage:**
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+**Config:**
+```json
+"service": "http://172.18.0.1:9090"
+```
+
+## Solution 2: Host Network Mode (NEW - Recommended for Linux)
+
+**Files:**
+- `Dockerfile.tunnel-only-v2`
+- `docker-compose.tunnel-only-v2.yml`
+- `config.tunnel-only-v2.json` (uses `localhost:9090`)
+
+**How it works:**
+- Container runs in host network mode
+- Can access `localhost:9090` directly as if running on host
+
+**Usage:**
+```bash
+docker-compose -f docker-compose.tunnel-only-v2.yml up --build
+```
+
+**Config:**
+```json
+"service": "http://localhost:9090"
+```
+
+**Note:** Host network mode works best on Linux. May have limitations on Windows/Mac.
+
+## Quick Test Guide
+
+### 1. Rebuild and restart with updated config (Solution 1)
+```bash
+# Stop current tunnel
+docker-compose -f docker-compose.tunnel-only.yml down
+
+# Rebuild with updated config (now uses 172.18.0.1)
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+### 2. Or try host network mode (Solution 2)
+```bash
+docker-compose -f docker-compose.tunnel-only-v2.yml up --build
+```
+
+## Expected Success Output
+```
+INF Registered tunnel connection connIndex=0 connection=xxx event=0 ip=xxx location=bom protocol=http2
+INF Registered tunnel connection connIndex=1 connection=xxx event=0 ip=xxx location=bom protocol=http2
+INF Registered tunnel connection connIndex=2 connection=xxx event=0 ip=xxx location=bom protocol=http2
+INF Registered tunnel connection connIndex=3 connection=xxx event=0 ip=xxx location=bom protocol=http2
+```
+
+**No "Unable to reach the origin service" errors!**
+
+## Test the Connection
+
+### From outside Docker (your current working test):
+```bash
+curl 172.18.0.1:9090
+# Should return: Monaco Code Execution Server v1.0.0
+```
+
+### From the tunnel (once running):
+```bash
+# Test via the public URL
+curl https://api.ishikabhoyar.tech
+```
+
+## Troubleshooting
+
+### If Solution 1 still doesn't work:
+1. Check if Docker bridge IP changed:
+   ```bash
+   docker network inspect bridge | grep Gateway
+   ```
+2. Update `config.tunnel-only.json` with the correct IP
+
+### If Solution 2 doesn't work:
+- Host network mode may not be fully supported on your OS
+- Fall back to Solution 1 with correct bridge IP
+
+### Check tunnel logs:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml logs -f
+```
+
+### Verify backend is accessible from Docker:
+```bash
+docker run --rm alpine/curl:latest curl http://172.18.0.1:9090
+```
+
+## Summary
+
+**Current Status:** ✅ Config updated to use `172.18.0.1:9090`
+
+**Next Step:** Rebuild and restart the tunnel:
+```bash
+docker-compose -f docker-compose.tunnel-only.yml down
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+The tunnel should now successfully connect to your backend! 🎉

+# Quick Start - Tunnel Only Mode
+
+## What This Does
+- Runs **only** the Cloudflare tunnel in Docker
+- Your backend runs **outside Docker** on port 9090
+- Tunnel forwards traffic from `api.ishikabhoyar.tech` to your local backend
+
+## Quick Start
+
+### Step 1: Start your backend on port 9090
+```bash
+PORT=9090 go run main.go
+```
+
+### Step 2: Start the tunnel
+
+**Windows (PowerShell):**
+```powershell
+.\start-tunnel-only.ps1
+```
+
+**Linux/Mac:**
+```bash
+chmod +x start-tunnel-only.sh
+./start-tunnel-only.sh
+```
+
+**Or manually:**
+```bash
+docker-compose -f docker-compose.tunnel-only.yml up --build
+```
+
+## Files Created
+
+1. **Dockerfile.tunnel-only** - Lightweight Docker image with only cloudflared
+2. **docker-compose.tunnel-only.yml** - Docker Compose config for tunnel only
+3. **config.tunnel-only.json** - Cloudflare tunnel config pointing to port 9090
+4. **start-tunnel-only.ps1** - PowerShell helper script
+5. **start-tunnel-only.sh** - Bash helper script
+6. **README.tunnel-only.md** - Detailed documentation
+
+## Test It
+
+1. Start backend: `PORT=9090 go run main.go`
+2. Start tunnel: `docker-compose -f docker-compose.tunnel-only.yml up --build`
+3. Test: `curl https://api.ishikabhoyar.tech`
+
+## Stop
+
+```bash
+docker-compose -f docker-compose.tunnel-only.yml down
+```
+
+## Troubleshooting
+
+**Backend not reachable?**
+- Check backend is running: `curl http://localhost:9090`
+- Check tunnel logs: `docker-compose -f docker-compose.tunnel-only.yml logs -f`
+
+**Tunnel not connecting?**
+- Verify credentials.json and cert.pem are valid
+- Check Cloudflare dashboard
+
+## Original Files (Unchanged)
+
+The original tunnel setup files are still available:
+- `Dockerfile.tunnel` - Backend + Tunnel in one container
+- `docker-compose.tunnel.yml` - Original compose file
+- These files still point to port 8080
