+# LXD Frontend (Nuxt.js)
+
+This is the **frontend Nuxt.js** application that works with the [LXD Proxy API](../backend/README.md) to dynamically provision LXD containers based on subdomain access and user CAPTCHA validation.
+
+---
+
+## 🌐 Overview
+
+- Each user has a subdomain (e.g., `testone.lxdapp.local`)
+- On visiting the subdomain, a login page prompts for CAPTCHA
+- Upon successful CAPTCHA, a request is made to the backend to:
+  - Create or start an LXD container
+  - Wait until it's ready
+  - Proxy user to the container
+
+---
+
+## 🧩 Features
+
+- Subdomain-aware dynamic environment provisioning
+- CAPTCHA login screen for triggering container creation
+- API integration with backend (Slim PHP) service
+- Axios-based POST to `/api/`
+
+---
+
+## 🛠 Project Setup
+
+1. **Install dependencies**
+   ```bash
+   npm install
+
+2. **Run the development server**
+    ```bash
+    npm run dev
+
+3. **Visit the subdomain**
+
+    http://testone.lxdapp.local:3000
+
+    ⚠️ Make sure this domain is mapped in /etc/hosts and that the backend is running on the correct origin.

+**🔐 CAPTCHA Flow**
+
+User opens subdomain: testone.lxdapp.local
+
+Enters the CAPTCHA value
+
+Form submits:
+
+POST /api/login with JSON payload:
+        
+    {
+    "source": "login",
+    "panswer": "abc123"
+    }
+
+Adds header:
+
+    Origin: http://testone.lxdapp.local
+
+**Backend:**
+
+    Validates CAPTCHA
+
+    Creates or starts container
+
+    Responds with container IP proxy
+
+
+**🧪 Development Notes**
+
+    config.json in backend maps subdomain to LXD container
+
+    This frontend app assumes the backend is on the same subdomain
+
+    If needed, configure proxy in nuxt.config.js or use relative API paths
